Editorial

The civilian-available semi-auto versions of what began as expensive SBR's (short-barrel rifles) or true submachine guns are advertised as having good accuracy and reliability while offering a more compact package than a rifle and higher round counts than most handguns. For the task of guarding the castle, we've been around the block a time or two, and have suitable choices for nearly anyone — great pistols, rifles, and shotguns. For this test, we had to suspend any preconceived notions of what we might prefer for home defense and test these firearms based on their own merits. Those merits, we found, are few. If you are shooting for fun and simply making brass, anything that goes bang is suitable. We'll get into the reasons for these judgments, but we like to be clear up front. The SIG Sauer MPX-P is one expensive means of not accomplishing much. The Uzi Pro pistol has drawbacks that made shooting downright frustrating. The MasterPiece Arms Defender proved to be the best of the three and has merit in a defensive situation, within certain narrow parameters. We arrived at this decision by using personal-defense criteria as the overriding factor in providing Buy/Don't Buy advice to our loyal readers. So, in more detail, here are our reasons for making these assessments. Our 9mm Luger ammunition for this test included a 158-grain lead round nose choice from Tomkatammo.com ($18/50 rounds). We also used Black Hills Ammunition 124-grain jacketed hollow points from VenturaMunitions.com ($14/20), a Black Hills Ammunition 115-grain EXP, an Extra Power load not quite in +P territory, also available from VenturaMunitions.com, ($17/20), and a SIG Sauer 115-grain full-metal-jacket load from Cabelas.com ($28/50). Others included the SIG Sauer 124-grain V Crown jacketed hollow point from Luckygunner.com ($16.75/20), and the Hornady American Gunner 124-grain XTP +P from MidwayUSA.com ($14.79/20). We used the Tomkat 158-grain, the Black Hills 124-grain JHP, and the SIG 115-grain FMJ load in benchrest accuracy testing.

It could be argued that the AR pistol evolved out of a desire and need for shooters to own a legal short-barrel rifle-caliber weapon without having to jump through BATFE hoops or pay for a tax stamp to own an SBR (short-barreled rifle). The difference between an AR rifle and pistol comes down to the pistol not being compatible nor able to attach a stock. We wanted to take a look at these AR pistols for home defense and other uses where a compact firearm makes sense, because they offer a number of benefits over a conventional AR rifle, mainly, being more maneuverable while being chambered in a rifle caliber and being compatible with common AR-15 magazines. We acquired three examples, a Spike's Tactical The Jack custom build, a CMMG Mk4 K, and a Kel-Tec PLR-16. The Spike's and CMMG are true AR-15 mechanisms reconfigured to a pistol, while the Kel-Tec uses a different operating mechanism. All three are chambered in 5.56mm NATO/223 Rem. and all are compatible with AR-15 magazines.

We tested these pistols for accuracy, performance, reliability, compatibility with a range of AR-15 magazines, maintenance, ability to be customized, and cost. We found that the Kel-Tec was inexpensive compared to the CMMG and Spike's Tactical pistols. The Kel-Tec, however, needed to be operated differently. The CMMG and Spike's were an easy transition from AR rifle to AR pistol. An AR pistol, as we found out, is nearly as effective as a full-size AR at close to mid range. With the right ammunition, they could be tuned to be a very capable home-defense choice for anyone in the family competent to operate a firearm. Namely, using frangibles to limit overpenetration through walls and doors while still supplying lots of pop.

The AR pistol's edge is its size, but it is also a disadvantage, as an AR pistol is not as easy to shoot as a rifle or a traditional handgun. They are large and require two hands to effectively deliver accurate shots. You could get off a few shots holding an AR pistol with one hand, but the weight of the pistol causes muscle fatigue. A typical full-size handgun may weigh more than 2 pounds loaded, compared to these AR pistols, which weighed from 3.2 to 6 pounds unloaded. Add a pound or more for a 30-round magazine, and you've got a sidearm that would wear out nearly anyone who didn't transport them with a sling, just as you would with a rifle. We used one of the SIG SBX Pistol Stabilizing Braces ($149; SIGSauer.com) and found we liked to use the brace differently than intended, which we will get into shortly.

We also fired the pistols using a Blackhawk Storm Sling ($33.95; Blackhawk.com), a single-point sling with a built-in bungee cord, which many team members felt was an excellent way to carry and control the pistol. We tested with three different AR-15 magazines, including a Brownells USGI CS (Brownells.com; $14) constructed of aluminum, and two polymer magazines, the Magpul PMag Gen2 (Brownells.com; $12.30), and the FAB Defense Ultimag (TheMakoGroup.com; $25). For fast reloads, we also used a Kydex AR magazine carrier from IBX Tactical (IBXTactical.com; $35).

Building an AR pistol is not just a matter of installing a short barrel in a upper receiver and swapping out the receiver extension/buffer tube. Short barrels lose velocity and provide less dwell time for the projectile, so manufacturers need to tune and time the mechanism. A short barrel also needs to work on a range of loads from low- to high-quality ammunition. Reliability can be an issue.

Hands down, the CMMG and Spike's offered more customization than the Kel-Tec because they are compatible with a range of AR-15 aftermarket products — triggers, rails, pistol grips, BUIS, and more. The Kel-Tec is not as compatible. Also, for those testers already familiar with an AR-15, the CMMG and Spike's were much easier to maintain. But there's much more to consider, which we relate below:

Maura Healey, the attorney general of Massachusetts, recently rewrote the state's 1998 Gun Control Act to reinterpret what it had meant since 1998. Healey explained how she would now enforce the state's gun law. The Massachusetts assault weapons ban prohibits the sale of specific weapons like the Colt AR-15 and AK-47 and explicitly bans "copies or duplicates" of those products. "Copies or duplicates" mean "state compliant" versions of Modern Sporting Rifles sold in Massachusetts, which might lack a flash suppressor, a folding or telescoping stock, or other features. The effect could mean that all AR-15s that have been modified to comply with Massachusetts law are now illegal purely because they are AR-15s.

The 3rd Circuit Court of Appeals has issued a decision that upholds the exclusion of certain firearms from the protection of the 2nd Amendment. In 2014, Pennsylvania resident Ryan Watson filled out an application on behalf of a trust to make and register an M-16/style machine gun with the ATF. Despite a federal law prohibiting any individual from manufacturing or possessing a machine gun after 1986, the ATF inadvertently approved his application. Afterward, Watson had his machine gun manufactured. A month after that, he received a call from the ATF saying that his application had been "disapproved."

As a carry handgun, the Glock is rugged, reliable, and combat worthy. About the only modifications that actually improve the Glock are the addition of a better trigger and a set of aftermarket sights. We dealt extensively with the issue of trigger replacements in the April 2014. There, we installed a Zev Technologies' GlockWorx Ultimate kit from Brownells.com ($250, #100-006-566WB, Mfr. Part: ZTFULULT4G9BLK) into our Glock 17. We gave the Ultimate Kit an A grade, saying it "was the upgrade that produced the biggest difference in performance all by itself, increasing the accuracy of the Glock 17 from an average grouping of 2.3 inches down to 1.6 inches."

Also in the April 2014 issue, we looked at two sight-upgrade kits, both from Brownells. One was the Brownells Glock 17 Sight Upgrade Kit ($200, #080-000-919WB), which included a Meprolight (Kimber) ML-10224 Tru-Dot Night Sight System for Glock 17, 19, 22, 23, 31, 32, 33, 34, 35, 37, 38, 39; an MGW Glock Sight Adjustment Tool, and an Ed Brown Front Sight Tool for Glock. Since we had the installation tools handy, we also ordered a set of TruGlo tritium fiber-optic Brite-Sites ($90, #902-000-107WB, Mfr. Part: TG131GT1Y), yellow rear and green front. We chose to put the TruGlo sights on the Glock 17 and the Tru-Dots on a G34 so that we could shoot them side by side.

With the Ed Brown Front Sight Tool for Glock ($20 sold separately, #087-017-001WB, Mfr. Part: 952) and the MGW Glock Sight Mover ($100 sold separately, #584-045-017WB, Mfr. Part: MGW309) for the rear sight, we started the switch with a disassembly of the slide to get access to the front sight. With the Ed Brown front sight tool and a small crescent wrench, we loosened the screw beneath the sight and removed it, then replaced the white dot with the new TruGlo front sight and tightened with the crescent wrench. Once the front sight was swapped, we hooked the slide into the MGW. The device came with some thin plates to raise the slide up the right height. We did not need them. The old sight drifted out with relative ease, going left to right pointed away from us. The new rear TruGlo sight did require some minor fitting with a file and a little more strength to slide in, but with the MGW tool, leverage was not a problem. We used the same process to put the Meprolite sights onto a factory Glock 34.

Despite the new TruGlo sights being fixed like the originals, we found them to be much clearer and easier to acquire and reacquire targets. We took to the range with the TruGlo sights installed, using all other original parts, and we cut our average group size down by almost half an inch, from 2.3 inches with the standard Glock to 1.9 inches with the TruGlo sights. We turned down the lights over the shooters, leaving the targets illuminated to check out how much the tritium would glow in the fiber-optic sights. The green front sight was quite bright, while the rear yellow sights were significantly dimmer, although still visible.

The Meprolight Tru-Dots provided an even more impressive change on the G34. We shaved just over a full inch off our average group size at 10 yards once we installed them.

Upgrading fixed sights can seem like a challenge to someone who hasn't done work on pistols previously, but with these tools and the simplicity of Glock's designs, this upgrade is a great place to start if you want to attempt a DIY project. You can drift the sights out with a punch, which will save $100 for the MGW tool, but you risk rupturing the tritium capsules. The MGW mover requires oil on the crankshaft, but it made drifting the dovetail sights in and out so easy we quickly misplaced our punch set. Overall, we found the TruGlo sights to be a nice upgrade and would recommend putting them in place of the standard non-tritium sights on any factory Glock. We gave them a Grade: A ranking, along with the Meprolight Tru-Dot tritium.

Naturally, readers asked about other sights, so we began looking at more replacements we could test head to head, rather than as a general Glock upgrade. So, again working with Brownells, we assembled a sextet of night sights suitable for installation on various Glocks. Also, we believe you can broaden our recommendations to include other firearms of similar size — the visual presentation won't be appreciably different on different platforms — though the installation process may differ gun to gun.

I'm really bad about looking at the events in California, Maryland, New Jersey, Maryland, and other gun-restrictive states and getting pessimistic about the health of gun rights in the country. I was told recently that such pessimism is a sin, and though I'm not especially religious, I saw the truth in the statement. Devout folks should be optimistic as a part of their character, because they see and proclaim the Good News every day. A fellow named Rick told me that in the hot tub of the club I swim at. I'm usually resistant to being proselytized, especially when I'm not wearing pants, but we had a nice visit and parted friendly. His testimony prompted me to look around for some Good Gun News, which was remarkably easy to find and widespread.

I am rarely worried when I write these editorials, but this time I am. Here, we are all Brothers and Sisters of the Gun, a community of folks who like to read about, shoot, maintain, accessorize, and buy and sell handguns, rifles, shotguns, and parts. There are few, if any, anti-gun readers sitting in their parents' basements in their pajamas — really, what would be the point of subscribing? So, with that said, I'm simply doing my job here and filling this space with gun-rights-related material because, sadly, politics matter in our ability to enjoy firearms freely.

But any time Donald J. Trump's name gets mentioned, folks tend to get agitated for him, or about him, or against him. I'm merely making sure that my readers know what the putative Republican presidential nominee has to say about firearms because it might get overlooked otherwise. Straight from his website, here are the major points of Trump's recently released gun-policy ideas headlined "Defend The Rights of Law-Abiding Gun Owners."

All in, I'm heartened by Trump's positions. I'm eager to hear your thoughts on these ideas, and please suggest any others you might want to see him adopt if he wins the general election in November.

There's a lot not to like in Physicians Angelica Zen and Alice Kuo's opinion piece in The Washington Post entitled "Do you own a gun? Why your kid's doctor needs to know." It was published on April 1, but I'll avoid playing on the obvious joke there. In the story, the doctors discuss the risks of having guns unsecured in a home with children and the need for doctors to talk about the subject with patients. They spend several thousand words justifying such an intrusion into my business, but, short version, I'll take my own counsel instead of theirs, since I'm the guy who handles guns all day and they don't.

Did I take precautions when my kids were growing up to ensure they couldn't get their hands on test guns? Well, sure. That doesn't make me special. 99.9% of all gun owners do the same, and they're successful at it, based on the absurdly low gun-accident rates we see these days.

Perfect gun hygiene isn't really that hard: Don't put guns and ammunition where kids can get at them. I took the additional step that, when I was handling firearms in my home office (measurements, photos, and the like), I didn't have any ammunition for those firearms on site. Could the 15-year-old version of Darling Daughter have bought 45 ACP at school and brought it home? Yeah. Very unlikely. And the guns were in a safe if I wasn't home. So, there were better chances of being hit by a smoking meteor of death than her getting in my guns. Now, she's the skeet coordinator for the National Skeet Shooting Association in San Antonio. Must be a coincidence. Number-One Son has a creative side business he calls Young Guns Media, and he's acquiring quite the collection of firearms as his budget allows. He's obviously traumatized by growing up around guns all the danged time.

The 10mm Auto cartridge seems to be going through a renaissance. There is new ammunition being manufactured in velocities the 10mm was intended for, like in the newer SIG Elite Performance ammo, and firearms manufacturers such as Glock and SIG have offered new pistols chambered in the round, the G40 Gen4 MOS and P220-10, respectively. We wanted to take a look at the 10mm in a full-size pistol that we could easily open-carry on the back 40 or concealed under a jacket or coat for in town. Since there are numerous examples of 10mm pistols to test, we also wanted to see if a different platform favored the big-bore caliber.

As we tested, we gained renewed respect for the 10mm round. Some testers even thought the round may be a liability in a self-defense situation due overpenetration. If we were in a crowded mall and were able to get solid center-of-mass hits on an attacker, we wondered whether certain loads would overpenetrate and hit a bystander. We do think it is a good round to punch through vehicles with and to stop big bears, and we also feel it is an excellent hunting cartridge if kept to bow-hunting distances on feral swine, whitetails, and small black bears. Around bystanders, we would most likely stick with the 10mm Lite or 10mm FBI loads if we carried the 10mm concealed.

The 10mm Auto creates a maximum pressure in the range of 37,500 psi. Compare that to the 45 ACP, which has about 21,000 psi with 230-grain ball ammo. The round was the brainchild of Jeff Cooper and a few like-minded individuals who wanted better terminal ballistics than the venerable 45 ACP could produce. The 10mm Auto exceeds 357 Magnum power and is very close to that of the 41 Magnum. The 10mm Auto is a brute of a round with the type of recoil you would expect from a magnum revolver. The mythical Bren Ten was one of the first semi-automatic pistols chambered in the round. The pistol never really lived up to its expectations due to magazine difficulties and the 10mm Auto thoroughly trouncing the Bren Ten's mechanism. The 10mm Auto has such a fast-moving bullet that it tends wreak havoc with the pistol's recoil mechanism. Colt first chambered its 1911 Series 80 in the cartridge in 1987, and it caused receivers to crack where the slide stop fits into the receiver. A relief cut was made by Colt to fix the situation, and the company's pistols in 10mm ran fine thereafter. When the FBI adopted the round after the Miami-Dade shoot out in 1986 due to agents' underperforming handgun cartridges, the Bureau soon realized agents could not or had a hard time handling the recoil of the 10mm Auto. The Bureau had adopted the cartridge first, then adopted the S&W Model 1076, which was purpose-built for the round. The FBI's solution was to load the 10mm light, which made it more tolerable to agents. The 10mm loads became known as 10mm Lite or 10mm FBI. We all know the light 10mm load is nothing but a 40 S&W in a longer case. The 10mm Auto produces about 300 foot-pounds more energy than the 40 S&W when the 10mm Auto is loaded to its standard velocity, and it's even hotter with niche ammo like that from Buffalo Bore. The 40 S&W changed the way law enforcement looked at cartridges, and the 10mm Auto might have been forgotten if it were not for some diehard fans — one of whom is on theGun Testsstaff.

Our shooters chose three very popular platforms to test the 10mm Auto: a 1911 design from Rock Island Arsenal (RIA), the SIG P220 model, which custom gunsmiths have been converting to 10mm for years, and the large Glock frame, which has been chambered in 10mm since 1991. All of these pistols in other calibers, namely 45 ACP, have received high grades in the past from us, so our expectation was these pistols would perform, and they did. All the pistols ran exceptionally well, with no malfunctions or jams. That says a lot because some 10mm Auto pistols are finicky because factory ammo is loaded light, standard, and heavy. We used an assortment of ammo; two light loads from Federal and two standard 10mm Auto loads from SIG in the Elite Performance Ammunition line, that are much faster than the Federal's load. The Federal loads consisted of American Eagle 180-grain FMJs which clocked slightly over 1000 fps, and Personal Protection 180-grain Hydra-Shok JHPs, which had an average muzzle velocity of slightly under 1000 fps. The SIG ammo averaged well over 1200 fps, except for the V-Crown 180-grain JHP in the Glock. The Glock showed lower velocity across the board with all the ammos compared to the SIG and RIA. Note the Glock barrel is also half an inch shorter than the RIA and SIG barrels.

It is sad and worrisome, but nonetheless true, that four other justices did not and do not agree with Scalia's decision in the Heller case. So his passing puts that decision, and individual gun rights, at risk again. Other than in McDonald, the Supreme Court has chosen not to harden the effects of Heller in many additional decisions.

United States Supreme Court Associate Justice Antonin Scalia, author of the Court's landmark Second Amendment decisionHeller v. District of Columbia, died on February 13, 2016, at age 79. Justice Scalia was found dead of apparent natural causes at the Cibolo Creek Ranch, a resort in the Big Bend region south of Marfa in West Texas. According to the San AntonioExpress-News, Scalia arrived at the ranch on February 12 and attended a private party with about 40 people. When he did not appear for breakfast, a person associated with the ranch went to his room and found his body. We extend our condolences to the family.

We reported last month that effective Feb. 1, 2016, Virginia would sever concealed handgun permit (CHP) reciprocity ties with 25 of 30 states, likely affecting many Gun Testsreaders. Good news: The cancellation of reciprocity was moved back a month to March 1, about the time this issue arrives in your mailbox. Also, the Virginia Citizens Defense League, Inc., (VCDL), an all-volunteer, non-partisan grassroots organization defending the right to keep and bear arms in the state, said there was a package deal in the works between Governor Terry McAuliffe and the Republicans in the General Assembly dealing with 1) concealed handgun permit (CHP) reciprocity, 2) voluntary background checks at gun shows, and 3) those subject to a permanent domestic violence protection order.

A VCDL release said those three components would be represented by matching bills in the state's House and the Senate bodies. Under the reciprocity section, Virginia will now honor carry permits from all states. "This is considerably better than current law and something VCDL has been trying to get for at least seven years now," the group said in a release.

Because Virginia will honor all other states, Virginia CHPs will be recognized by all the states affected by the reciprocity cancellation, plus three new states will be given reciprocity status: New Hampshire, Georgia, and Colorado. Further, going forward, the State Police and the attorney general will have no say in how reciprocity is handled. If another state requires a formal agreement to honor Virginia CHPs, the new law requires the attorney general to enter into any such agreement.

In a startling move, Virginia Attorney General Mark Herring announced on December 22 that Virginia will sever concealed handgun permit (CHP) reciprocity ties with 25 of 30 states. This will affect hundreds, maybe thousands, of Gun Tests readers who reside in Tennessee and other states bordering the Commonwealth, and perhaps millions of people nationwide.

Effective Feb. 1, 2016, — about the time this issue arrives in your mailbox —Virginia will no longer honor carry permits from the following states: Alaska, Arizona, Arkansas, Delaware, Florida, Idaho, Indiana, Kansas, Kentucky, Louisiana, Minnesota, Mississippi, Montana, Nebraska, New Mexico, North Dakota, North Carolina, Ohio, Pennsylvania, South Carolina, South Dakota, Tennessee, Washington, Wisconsin, and Wyoming. The following permits will continue to be recognized: West Virginia, Michigan, Oklahoma, Texas and Utah. The move also means several states will no longer recognize Virginia's concealed-carry permits because they require mutual recognition of permits. Those include Florida, Louisiana, North Dakota, Pennsylvania, South Carolina, and Wyoming.

Speaking about this audit and update, Attorney General Herring said, "Virginia, and nearly every other state in the country, have recognized that carrying a concealed handgun is a significant responsibility that should be extended only to those who have gone through a process to prove a level of competency and responsibility."

"The standards for proving competency and responsibility are up to each state," Herring said, "and the General Assembly has established Virginia's standards for whom it considers capable of safely carrying a concealed handgun. Those standards should be applied evenly, consistently, and fairly to anyone who wants to lawfully conceal a handgun in Virginia."
