About the SIG Sauer P320
SIG Sauer is a Swiss-German firearms manufacturer with U.S. headquarters in Newington, New Hampshire. The P320 is a striker-fired, polymer-frame semi-automatic pistol built around a modular chassis system, designed for duty, home defense, and competitive shooting.
How the California versions differ
- The 320CA-9-M18-MS-CA features a 3.9-inch barrel in the compact M18 military-variant configuration, making it the most carry-friendly option of the three.
- The 320XF-9-BXR3P-MS-CA uses a 4.7-inch barrel on the full-size XF frame, offering a longer sight radius and greater grip capacity than the M18 variant.
- The 320X5-9-LEGION-MS-CA is the longest at 5 inches and belongs to SIG's Legion series, which typically includes upgraded internals, an X-series grip module, and Legion Gray finish aimed at competitive and advanced shooters.
- All three versions listed are chambered in 9mm and carry the MS designation, indicating they are optics-ready with a removable rear plate for direct-mount red dot sights.
- MSRP ranges from $779 for the M18 variant to $1,199 for the Legion, reflecting the differences in features and series tier.
Who it suits
The P320 family suits a wide range of buyers, from everyday carriers looking for a proven compact pistol to competitive shooters who want a full-size, optics-ready platform with premium components.
