RB Glock 19 Barrel Black Nitride 9mm

Purchased this as part of a P80 build. Original barrel that was shipped did not fit the slide, nor would it fit a Glock OEM slide. Contacted RB with my issue. They had me return the barrel and immediately shipped out a replacement barrel. The new barrel fits great. Can't say much about the quality of the barrel as I haven't been able to get to the range yet, but the customer service is great. Took less than a week for the whole process of getting the replacement. Great job RB and I'll continue to be a loyal customer.

So far so good. Bought this to complete a P80 build and shot it for the first time today. Took 50 rds of Winchester Service Grade 115-gr FMJ (the flat-nose rounds) and a hundred of Winchester white box 115-gr FMJ (round-nose). Lubed the gun according to instructions and used Glock 15-rd mags. First two mags (flat-nosed) were problem-ridden, with stovepipes, double-feeds and failure of slide to return to battery. Third mag (round-nose) had problems, but fewer. Fourth mag (round-nose) ran problem-free, as did all subsequent mags including the rest of the flat-nose rounds. Accuracy was good, with the group low and to the left, but still inside the six-inch circle; I ascribe this to the standard Glock trigger and my unfamiliarity with it, and the fact that it was hot as hell outside today. The stoppages I ascribe to the break-in of the gun as a whole. Giving it four stars instead of five because I need to shoot it more, and if it proves to be as good as I think I'll be happy to upgrade to five stars.

Works as described, no accuracy issues. I would buy again

Great barrel, works just as good as a expensive barrel, nice inside design, and fit perfect

I bought this as part of a build kit. The coating seems good and the fit is fine. I did find that with mine (I don't know if all barrels are the same) the chamber is very tight. I reload and had to reduce my usual 9mm OAL and crimp settings from what I had been using for other pistols. However, the 2 different factory rounds (FMJ and JHP) I had on hand fed and functioned fine.
