The Unofficial P64 Resource Forum

I swapped out the recoil and hammer springs (both now 20 lbs) but was curious to know what the stock poundage is for the original ones.

Also, Wolff sent me another spring with the recoil spring but I can't tell what it's for. It's wimpier than the hammer spring.

Thanks,

The standard recoil spring is 18lbs while the standard hammer spring is 24lbs. If you ever need a reference check Wolff's page.

That extra spring that came with the recoil spring is a firing pin spring, it's made to match the extra force of the new recoil spring. If you replace one, you should replace both before you shoot it again. You can do this by starting on page 18 of the manual and working your way backward to switching the firing pin spring, and then forward to 18 to put it all back together again.

Thanks, Weasel!
