The SAS variant features an SRT trigger action, anti-snag treatment on the slide and frame and no rail.

Analysis

This .45 Auto pistol offers a robust design tailored for shooters seeking a full-sized duty or personal defense firearm. Its accuracy is commendable, delivering tight groupings at typical engagement distances, thanks to a well-engineered barrel and sight system. Ergonomically, the grip fits a wide range of hand sizes, providing a secure hold under various conditions. Reliability is a key asset, with consistent performance across thousands of rounds, even in adverse environments. However, maintenance can be somewhat demanding, requiring meticulous cleaning to prevent wear on critical components. Availability of replacement parts may pose challenges for some users, particularly outside major markets. The trigger pull is crisp, averaging around 4.5 pounds in single-action mode, though some may find the double-action pull heavier than preferred. Felt recoil is manageable for most, though newer shooters might notice a pronounced kick due to the potent caliber.
