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

Works great! Dropped it in the slide, made sure it locked in. Took it out, oiled the recommended points reassembles and put over 200 rounds through it. I highly recommend it.
