Overview
The SIG Sauer P225-A1 is a slim, single-stack 9mm DA/SA compact pistol reintroduced in 2015 as a modernized version of the classic SIG P225, also known as the P6 in West German police service. The original P225 was developed in the late 1970s for the West German police pistol trials (which it won alongside the Walther P5 and HK P7) and served as a standard-issue sidearm for numerous German and Swiss law enforcement agencies. The A1 update retains the proven short-recoil, locked-breech operating system with an aluminum alloy frame and stainless steel slide, but incorporates modern refinements including a slimmer profile measuring just 32mm in width, SIG's Short Reset Trigger (SRT) for a crisper trigger break with reduced reset distance, SIGLite night sights, an M1913 accessory rail, front cocking serrations, and a Nitron finish on the slide. Weighing 864 grams unloaded with a 91mm barrel, the P225-A1 feeds from single-stack 8-round magazines, making it one of the slimmest full-metal 9mm pistols available for concealed carry. The DA trigger pull measures approximately 44 newtons (10 lbs) with the SA pull at approximately 20 newtons (4.4 lbs).

Notes
The P225-A1 was discontinued around 2020 as market demand shifted toward higher-capacity polymer-framed pistols like the P365. The original P225 was introduced in 1978 as SIG's entry into the West German police pistol trials, where it was adopted as the 'P6' alongside the Walther P5 and HK P7 as standard police sidearms. The A1 designation indicates the 2015 modernization, which slimmed the profile by approximately 3mm compared to the original P225 through a redesigned grip and thinner slide. Two sub-variants were offered: the P225-A1 Nitron with a polymer grip and the P225-A1 Classic with traditional wood grips and a heavier slide. The P225-A1 shares many parts with the P226 and P229, including the fire control group and many springs, making it well-supported by aftermarket parts suppliers. MSRP was approximately $1,032 at introduction. The P225-A1 was manufactured at SIG Sauer's Exeter, New Hampshire facility, though the design originated from SIG's German/Swiss engineering heritage.
Background
The P225 holds a special place in European firearms history as one of three pistols selected by West Germany's police procurement board in the late 1970s. Designated the P6, it armed German police officers for over two decades. The A1 reintroduction was a nostalgic nod to SIG's classic DA/SA heritage, appealing to shooters who preferred the slim single-stack profile and all-metal construction over modern polymer alternatives. Its discontinuation marked the end of an era for SIG's traditional single-stack compact pistols.
