Flawless barrel after a little polishing for a p80 g17 slide - FM Products Ultra Premium Match Grade Glock Barrel

Purchased this FM barrel for a Polymer 80 G17 slide. After having tried a Brownell barrel that I returned because the rounds were jamming and not feeding, I thought I would give this FM a try. Initially, when I tried the FM barrel it was doing the same thing, not chambering rounds, jamming upon entry into the chamber. After that I decided to use a Dremel tool and polished the feed ramp on the barrel with some Flitz polishing compound until it shined pretty good then took the pistol to the range where it fired two 17 round mags without any issues. Hopefully that solved the problem for good. I have purchased other FM barrels previously and have found them to be top notch replacement barrels at reasonable prices. Maybe the Brownell barrel would have been OK after some polishing too. Even with a little work I still give this barrel five stars.
