I ordered an extra-power recoil spring and an 18lb hammer spring for my latest P-64 acquisition (Along with replacement springs for several other types of handguns). When they came in on Saturday I layed everything out and started replacing springs.
After putting the P-64 back together, I pulled the trigger back double action and found that it was WAY too easy - almost like a toy cap gun. I figured Wolfe had just mistakenly sent me the wrong hammer spring and I was going to have to reorder.
Then, this morning, I looked in the box and I found a package containing one 18lb P-64 hammer spring. Instantly I knew what I had done wrong. I had used the replacement firing pin spring that they always send with the extra-power recoill springs.
Thats funny, at least you figured it out before sending off a complaint to Wolff Gun Springs. Talk about a light strike on the primer! Did you even try it?
weetabix,
Yes, I have replaced the firing pin springs on both of my P-64's along with the recoil spring change. It's only purpose is safety.
When increasing the weight of the recoil spring you also increase the slide speed. The firing pin is an inertia type held back by the firing pin spring. If the spring were missing or too light the gun could conceivably fire (without the hammer dropping) when the slide cycles closed. It's most likely a liability issue for Wolff...and anyone who installs the recoil spring without installing the associated firing pin spring.
It's not difficult to do and gives you the opportunity to clean the slide internals while it is apart.

I have changed the firing pin spring each time I have changed the recoil spring on my P-64's. Wolff offers some fine springs.
This can be a pain in the........though! Do it right the first time. Read all about it here!
I now know my shop so well that I can guess where the missing spring might be! The big ziplock bag is a must for this the first time. I wish I knew that the first time I took one apart. No more missing parts.
Booooooinng!
