I want to start toying with my recoil spring. I'm considering adding 2 to 4 lbs. I shot a P228 with a 4lb heavier spring, and it was damn smooth. I'd like to tune up my 229. I know a little about springs, but would like some insight before I start tuning.
Recoil Spring - From what I understand, heavier than stock makes the gun run smoother. I've heard you want to run the heaviest spring you can while still enabling the gun to cycle fully and reliably with the ammo you shoot.
Magazine Spring - According to Wolf Gunsprings, if you go with a heavier recoil spring, you might want heavier magazine springs because there's less time for the magazine to feed a round. Couldn't this also cause problems with doublefeed though? Or would that only happen with stronger mag springs and a standard recoil spring?
Extractor Spring - I don't see how you could see benefits from tuning this away from stock. If it's weak, it's going to leave shells in the chamber, if it's at stock specs, should run reliably. Anyone with more insight?
Firing Pin Spring - This just pushes the firing pin back after firing. Wolf says they ship them with their stiffer recoil springs. What benefits/detriments would you see from changing the weight of the firing pin spring?
Mainspring - You want the lightest possible without having light primer strikes. For a carry gun, I think I would always leave this stock. Input?
