I recently received a Wolf 17 lb reduction recoil spring to replace the factory 20lb in my PPK. Along with the recoil spring was included a firing pin spring.
Maybe it's just me, but I don't feel much difference between the 17lb and 20lb spring.
I was also considering ordering a Wolf 17lb hammer spring to reduce the double action trigger pull.
Has anyone completed this setup ?
Can anyone help me with the installation of the firing pin and hammer spring or point me to a source?

Make sure about reliability before you bet your life on those spring changes.
I would also like to find out a source for COMPLETE dissassembly of the PPK.
Note also that lighter weight recoil spring means more wear on the frame/slide.

The ONLY problem I have ever had with Walther automatics is when the recoil spring suddenly "dies".

There is no preceived change in the strength of the spring, but the hammer starts to ride down with the slide. I believe the extra jolt caused by a weakend spring knocks the hammer off the sear.

I have had this happen with every PP series gun I have owned....PPK/S .380, PPK .32 and a .22 PP. I changed alot of parts around before I realised it was the recoil spring. In EVERY instance replacement of the recoil spring solved the problem.

I would not mess with the standard spring on a .380, especially since that cartridge provides these little guns with the biggest thump. Unless you are shooting squib loads or blanks I cannot see the reason to reduce the tension on the recoil spring.

P.S. Stiff pull be dam*ed, don't mess with the hammer spring either!

153:Bingo!!! Excellent point about recoil springs weakening!! As a matter of fact, I am gonna start a thread about this very item. Check it out

Ok, ya'll brought me back to the spherical plane. I have the tendency with a new gun purchase to research in an attempt to find a way to improve it, thinking I might know more than the engineers that designed the gun.
I was told by one of our range masters to let things be, as the designers knew what they were doing. Guess I need to listen.
I did file and polish the back of the slide, hoping to reduce the "bite" and polished the feed ramp, but I will let everything else factory.
Thanks for the replies.

Oh, sorry, I did leave out just one more change to the PPK. I purchased a pair of Hogue kingwood grips. The grips are a tad thick, but feel very secure in the hand.

I think you'll find the thicker grips are a distinct aid in shooting.

One quick update...the one time when you might consider a different power recoil spring is when you are using an "exotic" ammunition like Glaser. Many times the only way to get that kind of ammo to function reliably is to keep trying lighter weight recoil springs until you find the one that works. I just bought some Extreme Shock ammo and I may have to use a lighter recoil spring for that. Have to go out to the range and see how well it digests it

I like to leave it the way the engineers designed it, especially for a CCW gun.

The engineers designed it for FMJ ammo. Hardly something you should be betting your life on for self defense.
