watlow Posted September 4, 2016 Share Posted September 4, 2016 Gun has about 20k rounds down the pipe and we are having lockup issues. Time for a new recoil spring and extractor. Any thing else I should consider?....other than new springs every year instead of breakdown maintenance? Link to comment Share on other sites More sharing options...

Chris777 Posted September 21, 2016 Share Posted September 21, 2016 Sounds about right, I would also add the USB spring & new striker assembly, new trigger return spring. Also a good time to change out your FO if you have one. Link to comment Share on other sites More sharing options...

MemphisMechanic Posted December 9, 2016 Share Posted December 9, 2016 Mine is at 40,000 ish now. It got a SSS tool steel extractor hand fitted early on, because the 2007-ish 9Ls were having hideous extraction issues. It got the current striker design because the original ones broke in dryfire remarkably rapidly, again within the first 2,000 rounds. Since then it's worn out three 13lb recoil springs... and that has been all I've done. Link to comment Share on other sites More sharing options...
