Design
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.[3] 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.[2]
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 fourteen rounds, unlike the eight-round capacity of the P220. The P227 is a double-action/single-action-operated handgun, meaning that the first trigger pull is a ten-lb double-action pull, but all the follow-up shots are a 4.4-lb 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.[4]

Adoption
In 2013, the Indiana State Police adopted the SIG Sauer P227 Full Size Nitron as its department-issued sidearm. The contract calls for over 5000 P227 deliveries by the end of 2014.[4][6]
In 2014, after extensive .45 ACP weapon testing involving several manufacturers, the Pennsylvania State Police selected the P227 as its department-issued sidearm.[7] The Pennsylvania State Police replaced the P227 with the Walther PDP in 2024.
The Connecticut State Police and Delaware State Police currently issue the P227 as its standard duty pistol.
