Description
This is the Sig Sauer P365-FUSE COMP, the compensated version of the popular P365-FUSE. This model combines a full-size grip and slide length with a built-in compensator to reduce muzzle rise, making it a flat-shooting, high-capacity carry option. We started stocking these in late 2024, and it’s become one of our steady sellers in this category. The compensator is integrated into the slide, so you don’t need a threaded barrel or a separate add-on. It’s for anyone who wants the control of a full-size gun with the concealability of a compact.
Key Highlights
- Integrated Compensator: Machined into the slide to reduce muzzle flip and follow-up shot time.
- 17+1 Capacity: Comes with two 17-round flush-fit magazines standard.
- Optics-Ready Slide: Cut for the Sig Romeo-X and other micro red dots with a removable cover plate.
- Flat Trigger: Sig’s flat-faced trigger with a clean break and short reset.
- Lightweight Carry: Staff note: ‘The weight is barely noticeable once installed. Under an ounce of added carry weight.’ On our scale, the compensator portion adds just 1.2 oz total.

What Buyers Ask
Does the compensator require any special ammunition?
No. It works with standard 9mm 115-grain and 124-grain loads. The compensator is designed to function with normal pressure ammo, though you’ll notice the most benefit with NATO or +P loads.
Is this compatible with existing P365 holsters?
Generally no. The slide is longer than a standard P365 or P365 XL, so you need a holster specifically for the FUSE model. The compensator is built into the slide, so it doesn’t add extra length beyond the slide itself.
Can I swap the grip module for a standard P365 grip?
Yes. The FUSE uses the same FCU (fire control unit) as all P365 models. You can swap to a standard P365, XL, or X-Macro grip module if you prefer a shorter grip. But the compensator remains on the slide.
