Description
The SIG Sauer P365 BXR3P MS 9mm 3.1in Optic-Ready 2x10rd is a micro-compact striker-fired pistol built for urban carry where every inch of concealment matters and threats can close fast. Factory-cut for Shield/RMSc optics and fitted with XRAY3 day/night sights, this handgun gives you immediate target acquisition in low-light stairwells or parking garages. Two 10-round magazines keep you ready while staying compliant with capacity limits. At $499.99, it delivers SIG reliability without the premium price tag—a solid choice for apartment dwellers who need a carry gun that works as hard as they do.

Key Features
- Optic-Ready Slide: Factory-milled for Shield/RMSc optics so you can mount a red dot without sending the slide to a machine shop—critical for urban shooters who need speed over irons.
- XRAY3 Day/Night Sights: Tritium front and rear with high-visibility rings let you align sights in pitch-black hallways or bright sunlight without switching batteries.
- Manual Safety: Positive thumb safety adds a layer of security for appendix carry or storage in a nightstand drawer where kids or roommates might access it.
- Two 10-Round Magazines: Flat and extended floorplates give you grip options while keeping capacity at 10 rounds—perfect for states with magazine limits or urban environments where printing is a concern.
- 3.1-Inch Barrel: Balances ballistic performance with a short enough profile to conceal under a t-shirt or hoodie, even when sitting in a car or at a desk.
Who It’s For
Urban CCW holders who carry daily in dense cities, apartment dwellers who need a reliable home-defense pistol that doubles as a carry piece, and shooters who want an optic-ready micro-compact without paying custom-milling fees.
Pros & Cons
- Pro: Factory optic cut saves you $75-$150 in aftermarket milling costs.
- Pro: Manual safety gives you an extra layer of control in high-stress draws.
- Pro: Two magazines included—no need to buy spares immediately.
- Con: The manual safety lever is slightly stiff out of the box; expect 200-300 rounds of break-in before it feels natural. According to SIG Sauer specs, this is intentional to prevent accidental engagement.

FAQ
What optics fit the SIG Sauer P365 BXR3P MS?
This pistol is factory-cut for the Shield/RMSc footprint. That includes optics like the Holosun 407K/507K, SIG Romeo Zero, and Shield RMSc. Do not force a larger RMR footprint—it will not mount without an adapter plate.
Does the manual safety affect holster compatibility?
Most modern P365 holsters accommodate the manual safety. Brands like Vedder, Tier 1 Concealed, and SIG Sauer’s own holsters are designed to clear the safety lever. Always verify with the holster manufacturer before purchase.
Can I use standard P365 magazines in this model?
Yes. The BXR3P MS accepts all standard P365 magazines, including 10-round, 12-round, and 15-round extended options. The included two 10-round mags are compatible with any P365 variant.
Is this pistol California-approved?
As of April 2026, the P365 BXR3P MS is not on the California Roster of Handguns Certified for Sale. Check your local laws for compliance. We ship to all 50 states where legal.
What is the trigger pull weight?
The striker-fired trigger breaks at approximately 5.5 to 6.0 pounds per SIG Sauer specs. It has a short reset and a tactile wall, making it suitable for defensive use without being too light for carry.
