Frequently Asked Questions
Why upgrade your Sig P320 barrel?
Factory barrels work but NDZ barrels deliver match-grade precision, upgraded finishes, and threaded options for compensators or suppressors. Ideal for carry, range, or tactical builds.
Which P320 models are compatible?
NDZ offers barrels for Full-Size, Compact, and Carry P320 variants. Compatibility includes X-Series and standard slides. Always check product listings for exact fitment by size and slide cut.
Are threaded barrels available?
Yes, NDZ offers threaded and non-threaded barrel options. Threaded models typically feature ½x28 thread pitch for common muzzle devices and come with a thread protector included.
Do these barrels improve accuracy?
Yes. NDZ barrels are CNC-machined from quality steel with tighter tolerances and smoother bores, helping reduce group size and improve consistency shot after shot.
Are these drop-in or do they require fitting?
All NDZ P320 barrels are drop-in replacements, no gunsmithing needed. Just remove your existing barrel and install the new one.
