Threaded-Barrel 1911 Pistols: Some Choices Come Up Short

We tested a quartet of 45 ACP–chambered pistols with and without suppressors to see what worked and what didn’t. Outcome: Problems with function plagued half of the guns.

Threaded-Barrel 1911 Pistols: Some Choices Come Up Short

The Remington 1911 R1 Enhanced Threaded Barrel 45 ACP was fabulously accurate and dependable, other than during break-in. Our test team thought it was a great value for the money.

Last year, we began testing suppressors on rifles and handguns because we saw that the sound-abatement equipment was becoming a lot more popular. This was a surprise because suppressors are expensive and hard to transact, so it takes a lot of patience and money to get started, and there is a fair amount of legal liability if you get it wrong. Despite these drawbacks, since we began this journey suppressor regulations have become much more relaxed across the country, with all but a handful of gun-restrictive states allowing the devices. Still, it will take a couple of generations for suppressors to become mainstream and for the misconceptions about them to evaporate. For some, these unobtrusive pieces of hollow metal will always be tied to clandestine assassin or spec-ops use rather than as portable hearing protection. Pity, because during our testing with them, we have found a lot of salutary benefits behind the gun, whether long gun or sidearm. Suppressed firearms not only have shown better accuracy in most cases, they are certainly better mannered with a can hanging off the front. Muzzle flip and blast are easier to control with a can in place, and that improves accuracy and enjoyment.

We initially chose handguns chambered in 45 ACP because they offered a lot of full-power bullet weights and shapes that run below the speed of sound, so it’s easy to find good ammo that suppresses well. For the handguns, we started with three full-size non-1911 45s from Glock, HK, and FN, all of which come from the factory suppressor-ready. Reviewed in the September 2018 issue, we recommended the FN America FNX-45 Tactical FDE 66968 45 ACP, $1200. We had function trouble with a Glock G21SF PF2150203TB 45 ACP, $511, and didn’t recommend it. The third polymer gun was the Heckler & Koch Mark 23 45 ACP M723001-A5, $2300. It was big and expensive and very nice to shoot. Some of our testers said that if they were to buy the HK Mark 23, they would remember the day as fondly as when they got their favorite dog, which is high praise indeed.

Our 1911-style test guns this time included the Kimber America 1911 Warrior SOC 3000253 TFS with Crimson Trace Rail Master Laser Sight, $1309. We had loan of this immaculate early-model SOC with about 250 rounds through it, half of which were fired with an Osprey 45 suppressor like the one in this test. The Warrior SOC has an accessory rail built into the dust cover, which allows fitting a desert-tan Crimson Trace Rail Master laser as part of the package.

The second gun was a Remington 1911 R1 Enhanced Threaded Barrel 96339, $675, a recent in-stock price from TombstoneTactical.com. This was a well-outfitted gun for the money, coming with the 5.5-inch barrel threaded .578-28 like the others, two 8-round magazines with bumper pads, and a lot of other features we detail below.
