To the OP - Ya did good! It's a nice gun, now made nicer by a trip back to Glockland. You can't go wrong with a Gen2 G19, and these guns are made for SHOOTING, NOT COLLECTING. I, too, am a victim of many a cracked NFML magazine (both G17 and G19. I prefer mags that have to be pulled from the gun, and have paid a pre-ban premium for most that I have. I've had them crack while loading them, and crack after chambering a round (two rounds try to get out of the mag at the same time. I've also had them arrive that way from an auction purchase (usually a small crack coming from a round-count hole).
Pre-Gen3 Glocking is fun. We all have our own idea of "Glock Perfection".
