Great Barrel - Shoots good - Looks good by Lucky, Verified Owner, February 26, 2025
Bought the Nitride version of this barrel for my P365XL and paired it with a Griffin Micro-comp. Significantly improved an already great gun. Tighter groups for sure, and with the comp, less flip and quicker back on target for follow up shots. The...

Fine barrel but a slow one - followup by Phil, Verified Owner, October 15, 2022
Followup to my earlier review. My barrel mikes at .35535" (slugged) on my Mitutoyo micrometer. Suspecting possible roughness I lapped it extensively, which bumped most velocities a little. After lapping WIN Ranger 127-gr +P+ went from 1195 fps to 123...
