The Sig Sauer P365 is a striker-fired semi-automatic pistol built around concealed carry. Its compact frame packs a 12-round double-stack magazine into a package that measures 5.8 inches overall and 4.3 inches tall — notably high capacity for its size class.

Details 

The stainless steel slide with Nitron finish holds up well to wear and resists corrosion. Tritium night sights come standard, which matters for low-light use without any aftermarket work. The 3.1-inch barrel keeps overall length in check while still producing reliable velocity in 9mm. 
 
At 17.8 oz, the P365 is light enough for all-day carry. The grip texture is aggressive enough to maintain control during rapid fire without being uncomfortable for extended handling. 
 

Uses 

Primarily a carry pistol. The 12-round capacity is more than most competing micro-compacts. Home defense works too, though dedicated home-defense buyers may prefer a full-size gun. Competitive shooting is possible but not where this pistol is optimized.

The P365 draws consistent praise and some recurring criticism across owner reviews.

Compact size and concealability come up most often as positives — the slim profile fits easily under clothing and the 12-round capacity gives it a meaningful edge over single-stack competitors. Owners who prioritize high round count in a small package tend to be very satisfied.

The tritium night sights are well-received. Most owners report solid reliability across multiple ammunition types and no significant feeding issues.

On the critical side, recoil is snappier than with larger 9mm pistols, which is expected given the size but worth noting for less experienced shooters. Trigger feel gets mixed marks — functional, but not particularly crisp, and some owners add aftermarket components. Early holster availability was limited, though this has improved as the model matured in the market. Price sits above some competitors, which comes up occasionally though most owners consider it justified by the feature set.
