Owners of the Fusion XP Comp tend to highlight the flat trigger as one of the cleaner out-of-the-box triggers available in this price range. The fiber optic front sight gets good marks for visibility in daylight, though a few shooters swap it for a blacked-out rear to sharpen the contrast.

The compensator is effective at keeping the muzzle flat during rapid fire, but the added length over a standard slide is noted by those who carry. The Glock magazine compatibility is a practical plus for shooters who already run Glock-pattern magazines in other pistols.

Build quality opinions are mixed. Some buyers are impressed by the Tenifer finish durability, while others feel the overall fit and finish falls short of what the price suggests. The two included magazines are appreciated, but the aftermarket support for the XP Comp is thin compared to mainstream platforms.
