About the Sig Sauer P365
The Sig Sauer P365 redefined micro-compact capacity by fitting 10 rounds into a frame barely wider than a single-stack pistol, with 12- and 15-round magazines sold as upgrades. XRay3 day and night sights come standard, the trigger breaks cleanly for a factory striker design, and the stainless fire control unit is modular, so grip modules change without replacing the serialized part. Early production examples wanted a break-in period; current guns tend to run from the first magazine. The 3.1-inch barrel favors defensive hollow points designed for short barrels.
