Sig Sauer 3659BXR3PRS P365 9mm Luger 10+1 3.10"

The Sig Sauer P365 9mm is the micro-compact that changed the concealed-carry game—and this optic-ready variant takes it further. At just 5.8 inches overall and a shade under 18 ounces, it disappears into waistband or pocket carry without sacrificing capacity or shootability. The 3.1-inch barrel delivers the handling you need for defensive distances, while the striker-fired action gives you that clean, crisp trigger break Sig is known for. Rated for +P ammunition, the P365 handles hot loads without complaint, and the factory-cut optic slide accepts the popular Shield RMS-c footprint—letting you run a compact red dot right out of the box if you want one.

This isn't a gun that forces you to choose between concealment and capability. Two 10-round magazines ship standard—one flush-fit for carry, one extended for range work or backup capacity. The modular polymer grip and Nitron-finished slide give you a platform that's easy to maintain and built to last. Included XRAY3 Day/Night sights are crisp and reliable, and manual safety is available on this configuration for shooters who prefer it. The carbon-fiber barrel keeps weight down without any compromise on durability.

Whether you're a daily carrier looking for a truly concealable 9mm, a backup gun for duty use, or someone building a lightweight defensive pistol, the P365 has earned its reputation through millions of rounds fired in the real world. It's small enough to carry everywhere, powerful enough to handle the job, and versatile enough to run however you want to run it.

Frequently Asked Questions

Will this P365 work with a red dot sight?

Yes. The slide is factory-cut and optic-ready for compact red dots using the Shield RMS-c footprint. You can mount a compatible optic directly to the slide without modification.

Can I carry the P365 every day in a holster?

Absolutely. At 5.8 inches long and just 17.8 ounces, the P365 is one of the most concealable 9mm pistols available. It's designed specifically for everyday carry and works with standard holsters and carry rigs.

How many rounds does it hold?

The P365 is a 10+1 pistol—10 rounds in the magazine plus one in the chamber. Two 10-round magazines are included. Optional 12-round magazines are available separately and will give you 13 rounds total capacity (12 in the magazine, one in the chamber).

Is the manual safety required?

This configuration includes manual safety, which is a personal preference. Some carriers prefer it; others do not. It's there if you want to use it, but operation is identical whether you engage it or not.
