About This Firearm

The Sig P365-380 takes everything that made the P365 the best-selling micro-compact 9mm and chambers it in .380 Auto. It carries 10+1 rounds in a frame that measures 5.8" overall and weighs 15.7 oz, making it the highest-capacity subcompact .380 by a wide margin. The Ruger LCP MAX matches the 10-round count but does it in a true pocket gun with integral sights and no optic cut. The P365-380 ships with SIGLITE night sights, an optics-ready slide, a manual thumb safety, and two magazines. That optic compatibility is rare in .380s and lets you mount a micro red dot straight from the box.

The 6.3 lb striker-fired trigger is heavier than the S&W Shield EZ's 4.4 lb pull, and reviewers note it has more take-up before the wall. But the P365-380 is 2.8 oz lighter than the Shield EZ (15.7 vs 18.5 oz) and nearly an inch shorter overall (5.8" vs 6.7"). The Ruger Security-380 carries 15 rounds but weighs 19.7 oz and stretches to 6.52". Buy the P365-380 if you want the most features packed into a small .380 frame: night sights, optic cut, manual safety, and 10 rounds. Skip it if trigger pull weight matters more to you than size, because the Shield EZ has a noticeably lighter break in a slightly larger package.

Best For

GOOD
Concealed Carry
At 1.1" wide, 5.8" long, and 15.7 oz, it disappears in a quality IWB holster. The 10+1 capacity gives you 4 more rounds than most pocket .380s, and the SIGLITE night sights work in low light without a flashlight.
GOOD
Optic-Ready Carry Gun
The factory optic cut accepts Sig's ROMEOZero and similar micro red dots without adapter plates. Most .380s require aftermarket slide milling for optics. The P365-380 ships ready.

Strengths & Limitations

Strengths
  • 10+1 capacity in a 15.7 oz subcompact frame. The Ruger LCP MAX matches the round count but has no night sights and no optic cut.
  • Factory optics-ready slide is nearly unique among .380s. Only the Walther CCP M2 also ships with an optic cut in this caliber.
  • SIGLITE tritium night sights come standard. Most .380 competitors ship with basic white dot or integral sights.
Limitations
  • The 6.3 lb trigger pull is the heaviest among subcompact .380s in this group. The S&W Bodyguard 2.0 runs a 5 lb pull, and the Ruger LCP MAX is 5.8 lbs.
  • Shares the P365 frame dimensions but no magazine compatibility with the 9mm P365. If you already own a P365 in 9mm, you cannot share magazines between them.

Frequently Asked Questions

Can I use P365 9mm magazines in the P365-380?

No. Despite sharing the P365 frame, the P365-380 uses dedicated .380 Auto magazines. The feed lips are shaped differently for the .380 cartridge. Sig makes 10-round flush-fit and 12-round extended magazines specifically for this model.

Does the Sig P365-380 have the same recoil spring issue as early P365s?

No. The P365-380 launched years after Sig resolved the early P365 striker drag and recoil spring complaints. Community consensus from the first two years of production reports no widespread reliability issues specific to the .380 variant.
