SIG Sauer P227
The SIG Sauer P227 is an American-designed and produced semi-automatic pistol which was introduced in 2013 and discontinued in 2019. The P227 introduced a double-stack .45 ACP caliber handgun into the SIG Sauer lineup. It was introduced along with the P224.
The Sig Sauer P938 Nitron is an extremely reliable and concealable semi-auto pistol that offers the ballistic advantage of the battle-proven 9mm cartridge. The P938 Nitron features a black, hard-coat anodized alloy frame, and a Nitron coated stainless steel slide. Sig P938 pistols are modeled on a 1911-style, single action design, with an ambidextrous thumb safety. The hammer recesses into the beavertail section of the frame to protect it when carrying the weapon on safe, and to avoid hammer-bite while firing. The pistol operates with a locked-breech, short recoil action (instead of blowback) that locks the action closed. Slide serrations enhance the shooter’s ability to pull the slide back for loading and clearing the action. The Sig Sauer P938 Nitron Semi-Auto Pistol comes with SIGLITE night sights, dovetail to the slide, for rapid sight acquisition in any light, including total darkness. The compact P938 can be carried comfortably all-day—everyday, keeping it within reach for situations that call for rapid deployment of well-placed shots.

The P227 is similar in many ways to the P220 in .45 ACP that SIG Sauer introduced in 1975. It uses the same SIG Sauer designed short recoil locking system with their Single/Double Action trigger. The P220 is a full sized large pistol. The P227 uses a double row magazine for increased ammunition capacity and is very slightly larger to the point that it is not very noticeable. The action is automatically propped open after the firing of the last round in the magazine. The hammer, can be safely lowered by the decocking lever. Takedown is accomplished by removing the magazine, locking the slide open, and then turning down the takedown lever. The slide, barrel, and recoil spring will then slide forward off of the frame.
The P227 also features the new Enhanced Ergonomics ‘E2’ wraparound grip, rather than the two-piece grips of the P220. The P227 has a magazine capacity of ten rounds and one in the chamber, unlike the seven- or eight-round capacity of the P220. SIG also offers a fourteen-round capacity magazine, which is included in various models. The P227 is a double-action/single-action-operated handgun, meaning that the first trigger pull is a ten-lbs double-action pull, but all the follow-up shots are a 4.4-lbs single-action pull. The full size model is 7.7 inches in length (with a 4.4 inch barrel) and 5.5 inches in height with 1.5 inches in width. It weighs 32 ounces (907 g) with the magazine, features an accessory rail and three-dot contrast sights or SIGLITE night sights. The frame is constructed from anodized aluminum alloy with a Nitron finish and a milled stainless steel slide.
