FAQ

Is this a drop-in barrel, or will it require gunsmith fitting?
This is designed as a direct drop-in replacement for factory-spec P320 Compact/Carry slides. It should install without modification for proper headspace and function, but as with any part, function testing is always recommended.

Does this barrel work with optics-ready (PRO/Carry) slides?
Yes, as long as it is a standard 3.9″ P320 Compact or Carry slide, optics-ready or not, this barrel is compatible. The key compatibility factors are the model (Compact/Carry) and the 3.9-inch slide length.
