I always forget ....so I called Wilson Combat this morning ....and they advised every 5,000 rds on Firing Pin springs / and 2,000 rds on recoil springs.
I've been neglectful .....
and a tip on the firing pin springs - they reminded me ( there is a small end and a larger end -- the smaller end, goes on first ) or you may have some issues with firing pins sticking.. The Firing Pin Springs are the same / in all of their guns whether its a 9mm or a .45 acp ....but the recoil spring recommendations vary from 13 lbs on the 9mm to 16 lbs - 18 lbs on their .45 acp's. I like the 13 lb springs in my 9mm's / and I like my 5" .45 acps with 16 lb recoil springs.
