Sig Sauer P365 Fuse – Full-Size Capacity in a Concealable Compact Frame

Ace of Spades Armory proudly carries the Sig Sauer P365 Fuse – the newest evolution of the legendary P365 platform. This striker-fired 9mm pistol delivers full-size magazine capacity while maintaining true everyday carry dimensions.

High-Capacity Magazines Included

Every P365 Fuse ships with three steel magazines: two flush-fit 21-rounders and one 17-round magazine with extended base plate. Carry 21+1 rounds in the same grip length that made the original P365 famous.

Optics-Ready Slide with Shield RMS-c Footprint

The factory-milled slide accepts compact red dots using the popular Shield RMS-c footprint. Popular optics like the Holosun 407K, 507K, EPS Carry, and Sig RomeoZero Elite mount directly – no adapter plates needed.

Aggressive LXG Grip Module for Total Control

Sig’s laser-stippled LXG polymer grip module provides aggressive texture in all the right places. The undercut trigger guard and high-beaver tail give a higher, tighter grip that reduces felt recoil and improves accuracy.

Nickel-Plated Flat-Faced Trigger

The crisp, short-reset trigger breaks cleanly at approximately 5.5-6 lbs. The flat face and nickel plating deliver consistent finger placement shot after shot.

Fiber Optic Front Sight with Blacked-Out Rear

Co-witness your red dot or run iron sights alone. The high-visibility fiber optic front pairs with a serrated black rear to eliminate glare and speed up sight acquisition.

Accessory Rail and Aggressive Slide Serrations

The integrated M1913 Picatinny rail accepts weapon lights and lasers. Deep front and rear serrations give positive manipulation even with wet hands or gloves.

Compare the P365 Fuse to Other P365 Models

• Longer 4.3″ barrel vs the standard P365 XL (3.7″)
• Same grip length as the P365 XMacro (see our Sig P365 XMacro Comp for comparison)
• Slimmer 1.1″ width than the Sig P365 XMacro Tacops

Built on the Proven P365 Fire Control Unit

The serialized stainless steel FCU remains fully compatible with all P365 grip modules and slides – customize your Fuse later with parts from our Sig P365 Parts Section.
