Excellent machining and finish throughout. It feels like a high-quality factory component with precise construction and a clean appearance.
Now that running suppressed avoids the 200 tax stamp... its our time!

Great Barrel

by Kurt in Cypress, Verified Owner from TX, United States Written on April 2, 2025
Used this barrel on a P320 with a SIG mod X suppressor. Perfect fit, of course, and reasonably priced I believe. When ordering, make sure that you order the length that it is going to be with the thread protector on it. Don’t order based on your existing barrel length. I made that mistake.
Best Used for:
  • Sig pistols
