That is the route I took. Seriously.....I have shot Glocks a bunch and so far I have broken:
1 extractor (gun continued to run in a sanctioned match)
1 recoil spring assembly (the gun would not go into battery anymore)
1 trigger spring (doesn't stop the show, but still a pain)
All of these parts broke or wore out on the same Glock 17 after around 25K rounds of live fire and countless dry fires. I know that many will tell you of tens of thousands of rounds without having to replace anything....I guess they are lucky or treat their gun a bit better than I do. I have a 1911 to sit and admire....I abuse my Glocks
