The P365 TacPac pairs a 3.1-inch barrel with a striker-fired action in a micro-compact footprint, delivering a 12+1 capacity with the included 12-round magazines. The polymer frame with molded stippling provides a secure hold, and a push-button magazine release offers familiar, straightforward operation. Made in the United States, this configuration balances concealability with capable capacity.
Factory tritium night sights come installed, with a green tritium front dot and tritium rear, both dovetailed for durability and serviceability. Front and rear slide serrations support confident manipulation in varied conditions, and the Black Nitron slide finish adds corrosion resistance with a clean, low-glare look.
The TacPac bundle adds two 12-round magazines and one 10-round magazine, giving you flexibility for carry and range use. The included SIG Sauer polymer OWB belt holster makes it easy to head straight to the range, and the steel magazines are marked "MADE IN USA" for the P365.
