A tight slide-frame fit is nice on a bullseye pistol, but may induce failures on a "combat" pistol. Mechanical accuracy comes from a quality barrel that has consistent 3-point lockup, that means muzzle and bushing, barrel feet and slide stop pin, and barrel locking lugs and slide. Shooter enhancements to accuracy are a consistent trigger break and good sights.
