The Sig Sauer 40 S&W P320 Compact Caliber X-Change Kit is a factory magazine and conversion system built for shooters who want to run their P320 Compact in a different caliber without swapping the entire gun. This 10-round magazine kit lets you transition your P320 Compact platform to fire .40 S&W, giving you flexibility on the range or at the range without the cost of a second firearm. If you already own a P320 Compact and want to explore another popular defensive or competition caliber, this X-Change kit handles the heavy lifting.
Sig Sauer engineered the P320 platform around modularity—you can swap calibers, grip sizes, and slide configurations to adapt one gun to multiple roles. This particular kit bundles everything needed to chamber .40 S&W in your Compact frame, so your trigger control and ergonomics stay consistent even as you change ammunition and ballistics. For competitors, recreational shooters, or defensive-minded folks who like having options without buying a second pistol, it's a practical choice.
Magazine capacity is set at 10 rounds, so this kit works well for shooters in restricted states or anyone simply preferring a lower-capacity platform. Sig's manufacturing standard means reliable feeding and durability across heavy training sessions or occasional use. This is genuine modular shooting—one gun, multiple capabilities, one simpler safe to manage.
