Much popular opinion around handgun slides posits that slide tightening is not particularly important for maximum accuracy. Instead, barrel-to-slide fit and barrel and bushing fit are more frequently stressed. With some of the quick packages that the gunsmith offers, barrel and bushing fit are good enough for carry purposes, or perhaps even for IDPA-competition pistols. But when a shooter demands top-notch accuracy, his pistol should have a good tight slide and frame-rail fit.

Wilson Combat has introduced the T.R.I.M. AR-10-D (Tactical Rail Interface, Modular) AR-10 rail, which the company touts as the lightest, strongest and most versatile compact free-floating rail systems on the market. It’s available in 12-inch ($350) and 14-inch ($360) sizes. It is designed for AR-10 pattern rifles and clones with 1-7/16-18 inch threaded receivers, such as the DPMS/SR-25.

To answer a number of questions concerning the performance of the 1911 pistol, the Gun Tests South Carolina test unit obtained a Rock Island Armory Standard GI No. 51421 45 ACP, $410, and a Kimber Eclipse Target II 45 ACP, $1393, in what originally seemed to be a price mismatch.

Adaptive Tactical recently released Sidewinder Venom Shotgun Magazine Conversion Kits for Mossberg shotguns.

Small semiautos that match the physical dimensions of pistols we tested recently - such as Para-Ordnances $740 P12-45 - are usually referred to as compacts or sub-compact. But when pistols of this size class are miniaturized 1911s, the tag of "Officer's models" is hung on to them, even though they may not exactly fit the mold of the original Colt's Officer's model.

Manufacturers are taking a fresh look at the Officer's model for a number of reasons. For one, the 1911 pistol has legions of fans inside both competitive shooting and law-enforcement circles. Also, many military and ex-military personnel recognize the .45 ACP's superiority over the 9mm Parabellum, a cartridge choice often perceived as NATO's intrusion into American affairs. Traditionally the Officers model offered a six-round magazine, like the 945s. However, the Para Ordnance P12 integrates a double-stack or staggered-round magazine that holds ten rounds.

The P12 has been around a while and is essentially bug free. It fits the hand surprisingly well and points easily. Function was 100 percent despite warnings from some gunsmiths who seem weary of semiautos fitted with short slides. The P12 action also includes a Series 80-style firing pin block. This mechanism is not a favorite with 1911 purists, and some gunsmiths have a difficult time refining the action with this feature in place. But the P12 did not suffer any malfunctions because of it.

The San Antonio Police Department has selected the M&P40 as its new service firearm and has begun to convert officers to the new handgun platform. Gun Tests has its own rating of the pistol.

Gun Tests’ Idaho-based test team takes a detailed look at two carryable 40 S&W pistols in the May 2013 issue of the magazine. Sr. Technical Editor Ray Ordorica examined the Glock 23 Gen 4, $650, and the Taurus 24/7 G2C, $555.

Silencers, like machine-guns, are regulated under the National Firearms Act (NFA) of 1934, and are regulated by the Bureau of Alcohol, Tobacco, and Firearms. The procedure for owning a silencer may seem daunting at first, but actually requires less paperwork than buying an automobile.

The Glock 33, or G33, was chambered for 357 SIG and operated just like its medium- and large-size brothers, (models G32 and G31 respectively). The most notable difference was the short grip, which limited the shooter to holding the pistol with only two fingers. The rear of the stubby grip showed a generous palm swell and the trigger guard was generously undercut, or generously under-molded.

I recently ran across a fascinating copy of the U.S. Army’s “How to Shoot The U.S. Army Rifle” handbook, published in 1943. This book, subtitled The Infantry Journal, was prepared by First Lieutenant Arthur Goodfriend, creator of the Army's graphic portfolio on rifle marksmanship. The acknowledgements suggest how important the topic of shooting well was back then.

Ryan Cleckner shares his process for sighting in a scoped rifle. There are some basics here, including bore-sighting, starting with a short 25-yard shot to get on the paper, and shooting groups before making adjustments at 100 yards. Two items at the end are also worth considering: slipping the scales and finding mechanical zero.
