i recently bought a ruger police service six, i was wondering since its no longer made should i get extra parts? i don't plan on shooting much as this is my woods gun, i'll put about 20-50rds to get the feel then only a few rds a month if that, probably only fire it when its needed. do you think spare parts is needed because i know that soon they may run out? do ya'll keep any on hand? i have been checking and some springs are fairly easy to find, wolf makes a new hammer and trigger spring kit. but the firing pin and spring i can't find. probably never need them but peace of mind having them helps. if i just had the firing pin and spring i would feel better, the other stuff seems to be easy find. just the firing pin and spring seems to be bought up. thanks for any help.
