Glock Picture Thread in Weapons Posted April 23, 2008 · Report reply Thanks for the help ViciousV10s. Removed the blowback mech from the slide, fiddled, replaced and got it working, replaced slide on frame. But now the slide doesn't move at all. I've ordered another Pro arms frame which I'll either replace the current one with or sell on. Junior, what did you use to fill in the hole you had made in the mag well?
