W_Buck Posted January 30, 2012 Share Posted January 30, 2012 I've had my Shadow about a year and a half now, approx 10k-12k rounds. I haven't changed any springs in the pistol yet. I'm curious how often you guys change out certain springs. Recoil spring, main spring, extractor springs, mag springs etc... Quote Link to comment Share on other sites More sharing options...
burningsquirrels Posted January 30, 2012 Share Posted January 30, 2012 i'd do it now if you haven't already. i call it my 'annual maintenance'. i also try to do it in december, so that if any problems crop up, it happens during the dec-jan off season. plus, since the springs will be different than ones taht aren't worn out, you might need to get a feel for the fresh springs again. i change: recoil hammer firing pin spring extractor spring trigger return all magazine springs i inspect: slide stop extractor hammer/sear surfaces magazine feed lips with a micrometer magazine followers all roll pins on the gun i might've missed something but that's the gist of it.

W_Buck Posted January 30, 2012 Author Share Posted January 30, 2012 What's the idea behind changing the firing pin spring? Quote Link to comment Share on other sites More sharing options...

Joe L Posted February 17, 2012 Share Posted February 17, 2012 Burning Squirrel's routine is a good recommendation for any gun. I have finally got enough rounds through my P226s that I am starting to have some magazine spring related problems and I am just going to replace them all, once/year regardless of round count. I am setting up a recoil spring tester but those are also so inexpensive that it makes sense to replace them pretty often, probably 5k rounds for my 9mm SIG guns, more often for the 22, like when it won't chamber a round when the chamber is clean. Trigger springs, sear springs are not a problem with the SIGs, although I carry spares. Looks like the maintenance schedule for the CZ is going to be similar to the SIGs.

NOSAJ19 Posted February 18, 2012 Share Posted February 18, 2012 2007 model, CZ 75 SP01 Shadow. I broke a trigger spring @ 30,000 rounds. Never ever replaced any of my springs in the gun, including mags. It is not a 1911. Well over 100,000 rounds & counting. Quote Link to comment Share on other sites More sharing options...
