The Sig Sauer P365 is a striker-fired (DAO) micro-compact pistol chambered in .380 ACP. At 5.8 inches overall and 15.7 oz, it covers the same footprint as many subcompacts while holding 10+1 rounds. The black finish, tritium night sights, and RMSC optic compatibility make it a functional carry setup with no additional purchases required.

Detailed Features 

The micro-compact frame conceals easily under light clothing. The 10-round double-stack magazine in a micro frame is what made the original P365 notable when it launched -- this .380 ACP variant carries that same design. Tritium night sights give reliable low-light target acquisition without needing aftermarket upgrades. The polymer frame over a stainless steel slide keeps the weight at 15.7 oz while maintaining durability. The striker-fired action delivers a consistent trigger pull on every shot. The RMSC optic cut allows co-witnessed miniature red dot mounting for those who want a faster sight picture.

The P365 in .380 ACP with night sights draws a strong positive response from owners, balanced by a handful of recurring criticisms.

Most owners praise the size and weight as the primary reasons they chose it. The grip is noted as comfortable for a wide range of hand sizes, and the night sights are consistently well received for both low-light home defense and range use. Range performance -- including accuracy and reliability across different ammunition types -- comes up often as a positive. The striker-fired trigger appeals to shooters who prefer a consistent pull over a DA/SA transition.

Common criticisms: recoil in the compact .380 ACP frame runs snappier than in larger guns, and some shooters report occasional feeding issues, though these appear infrequent. Night sight brightness draws some criticism for not being bright enough in very bright environments for quick target acquisition. The overall discussion reflects a gun that owners trust for defensive use while acknowledging the recoil and minor reliability reports as real trade-offs.
