Sig Sauer P365 MS 9MM 3 1 Optic Ready 210 RD
About this product
This Sig Sauer P365 is the Optic Ready configuration with a manual thumb safety (SKU 365-9-BXR3P-MS), one of several variants Sig sells within its category-defining P365 micro-compact 9mm line. At $499.99, it's priced in line with the broader P365 lineup, with the manual safety and factory optics cut being the two features that set this specific SKU apart from Sig's base P365 models.
Why does this P365 have a manual safety when others don't?
Sig sells most P365 variants without an external manual safety, relying on the trigger safety alone, but this SKU adds an ambidextrous manual safety for shooters - or for states - that require or prefer one. If you specifically want or need a manual safety on a P365-pattern pistol, this configuration is built for that rather than requiring an aftermarket retrofit.
What does 'optic ready' mean on this model?
The slide is cut from the factory to directly accept a ROMEOZero Elite red dot without an adapter plate, using optic-cut technology licensed from ZEV Technologies. If you plan to run a different red dot footprint, confirm compatibility before buying a sight, since the direct-fit cut is specifically sized for the ROMEOZero Elite pattern.
What are the core specs?
It runs a 3.1-inch carbon steel barrel, an overall length around 6 inches, and an unloaded weight of about 18.3 ounces. XRAY3 day/night sights come standard, and the pistol is rated to handle +P ammunition if you choose to carry or practice with it. Two 10-round magazines are included.
Is a micro-compact pistol like this a good everyday-carry choice?
The P365 line built its reputation on packing a relatively high round count into a genuinely small, easy-to-conceal frame, and this manual-safety, optics-ready variant keeps that footprint while adding the safety lever and factory optics cut some shooters specifically look for. As with any carry pistol, grip fit and trigger feel are personal - handling one before buying is worth the time if you haven't shot a P365 before.
Sig's P365 line has expanded into dozens of configurations over the years - different barrel lengths, optics cuts, manual safety options, and calibers - and this specific SKU represents one of the more complete feature sets Sig offers in the original micro-compact frame size, combining the manual safety, optics readiness, and +P rating in a single package. Ammunition compatibility is standard 9mm Luger, and the pistol ships in a hard case with a lock, cleaning brush, and manual, consistent with how Sig packages most of its P365 lineup. If you already own or plan to buy a ROMEOZero Elite, this configuration removes the extra step of sourcing an adapter plate, since the slide is milled specifically for that footprint from the factory.
Sig has sold multiple P365 configurations onto California's approved-handgun roster over the years, but roster listings are SKU-specific, and this manual-safety optics-ready configuration may or may not currently be listed separately - confirm this exact SKU's current California status with your FFL before ordering.
How does the purchase process work?
As a firearm, this pistol must transfer through a licensed FFL dealer - it cannot ship to your home address. You'll complete a background check and any required state waiting period before taking possession. Checkout on this site runs through secure checkout, and FFL transfer fees are set separately by the receiving dealer.
FFL transfer required
This item is a firearm and ships only to a licensed FFL dealer, never to a home address. At checkout, enter your preferred dealer as the shipping address, or leave it blank and we will assign a licensed dealer near you at no extra cost. You complete the background check and paperwork with the dealer when you pick up.
California buyers: handguns must be on the California roster for delivery to a California FFL, a Firearm Safety Certificate (FSC) and DROS are handled at the dealer, and the 10-day waiting period applies. Out-of-state buyers receive the firearm through their own local FFL under their state's rules.
