SIG Sauer has a new kid on the block when it comes to its well-received P365 line that blends the expansion chamber compensator with the Fuse series – and ships with an installed optic. 

The 17+1 round (flush, 21+1 extended) capacity full-size Fuse was introduced to SIG's micro compact 9mm line in 2024 and has fared well in our extended testing – especially with the Romeo X "mailbox" style fully enclosed optic, which is what the new Fuse Comp model carries.

With its 3.7-inch carbon steel barrel stopping about a half inch shy of the slide, the new Fuse Comp shares the same integral compensator style as seen on the popular X-Macro Comp and Spectre Comp, designed to reduce muzzle rise and soften felt recoil. (Photos: SIG)
