The SIG Sauer P227, introduced in 2013 and discontinued in 2019, was a notable addition to SIG’s lineup, being the company's first double-stack .45 ACP caliber handgun. The P227 was available in three distinct models: Full Size, Carry, and SAS (SIG Anti-Snag). The Full Size model measures 7.7" in length with a 4.4" barrel and stands 5.5" tall, while its width is 1.5". It weighs 32 oz and features an accessory rail, along with either 3-dot contrast sights or SIGLITE night sights. Constructed with an anodized aluminum alloy frame and a milled stainless steel slide finished in Nitron, the Full Size P227 combines durability with a sleek appearance. The Carry and SAS models offer a more compact option, with overall lengths of 7.1", barrel lengths of 3.9", and an empty weight of 30.5 oz. The SAS variant is designed with all edges and sharp corners beveled for smoother handling, and it includes SIG’s Short Reset Trigger (SRT) for faster follow-up shots. Both the Carry and SAS models retain the traditional DA/SA trigger system. The P227 is equipped with a double-column magazine that holds 10 rounds of .45 ACP, with an optional extended 14-round magazine available to enhance capacity. This versatility and range of features made the P227 a prominent choice for those seeking a high-capacity .45 ACP pistol.
