Does anyone know where to get spring (mainspring) replacement kits for the HK USP Tactical?  I have been having problems with unfired rounds where the primer has a small dent but did not ignite the cartridge.  Other pistols do just fine with the same ammo (reloads).  I've put about 5000 rnds through the pistol so I was thinking maybe the spring needed replacing.  Any suggestions?

Wolf makes replacement springs, but it could be a bent firing pin.  I would punch the retaining pin out and check for (Burrs, Bends, Crud, Rust, or Broken Pin).

Im almost sure HK wont send you a part if it is the mainspring.

Heres the link to Wolf Gunsprings http://www.gunsprings.com/1ndex.html I would get the reduced and normal springs. Both will run you about $9 together.

Good luck my friend.
