I bought this barrel this past May and was very pleased with how accurate it is. But......it will jam while feeding pretty much every round. This rifle did run flawlessly with the previous 45 ACP barrel and after trying a number of different mags and swapping out the mag release, I came to the conclusion that the bottom rear edge of the chamber needs to be relieved a touch . I have polished it down just to where it started feeding the aluminum dummy rounds, so we'll see how it works at the range with live rounds. If it is still jamming a bit, I will polish down the extension a bit (ie Feed Ramp'ish). My lower is a Gibbz "branded" side charger that takes Glock 21 mags.

While I have not been able to shoot this gun yet. The Fit and Finish are Superb!
