I have several Glocks
19,17,22,30,30s,in gen 2-3-and 4 never had BTF in any of them. But let's say even if a specific model had 1type of a easily fixable malfunction does not take away from this being a great mechanical device. One of the best designs ever. Till hopefully now. With the coming of P 10 c
You're assuming that it's easily fixable, in some cases it's not. (I had one gen 3, g19, that I believe couldn't be fixed, an Apex extractor didn't help that much) I'm sure tolerance stacking is the major culprit here, along with Glock's Rube Goldberg ejection system. In my case, I managed to pick three G19's over a several year period (one Gen 3, two Gen 4's) and all had ejection issues. The last one being bought new, in November 2016.( I thought that by then, they had it all ironed out...not!) My one and only gen 4 g17 (LEO trade-in) has ran like a swiss watch, no BTF at all.. So, yeah, I've had a gut load of Glock, and their brass throwing machines... Please, no suggestions to call Glock, I did once, sent it in, (grey framed Gen4 G19 bought in 2014) they changed a few parts , I shot it when it came back, no improvement, called again, and pretty much got treated like dirt for calling. They showed zero interest in fixing it, I have zero interest in playing 'the game" with them where we send it back and forth until they decide to replace it, or actually fix it. Needless to say, I'm not real happy with them.. The P-10 can't get here soon enough.. And once I get the P-10 vetted as a CCW, I'll dump every G19 I own..
