RB Glock 20 Barrel Stainless Steel 10mm

Cheaper than most other G20 barrels out there, I haven't put many rounds through it, and of those they were .40 S&W not 10mm as the 10mm I bought (PMC Bronze 170 Grs. JHP 10B) would not feed at all from the magazine, it might be the barrel but it might not. The round would get hung up and jam, when the round was pulled out it had markings from the barrel on the brass, such as a crescent shape from the bottom and a queer cleft perpendicular to the cartridges mouth on the top. I don't know what might be causing that, but .40 S&W chambers and feeds with no hiccup. The 10mm that I previously mentioned would certainly *chamber* in that you could slide it in through the ejection port, but not feed.

Just as good as OEM if not better. Will buy again.
