New guy question on spring changes

herk · Post by **herk** » May 7th, 2007, 5:50 pm

I have read just about everything on the forum concerning spring changes since I bought my 1975 P-64 three days ago. When I picked up the gun the first time, I experienced double-action trigger shock and would have put it down immediately if I hadn't felt the smooth single action trigger. The more I looked at it, the more it grew on me. The price was right, the size was right, the caliber was good so I took the plunge and bought it. I was sure that the double action trigger could be improved and as it turns out, I was right. Objective- lighten double action trigger pull, do not lighten single action trigger pull, reduce felt recoil and have 100% reliability. My thoughts- change to 20-22# recoil spring to reduce felt recoil, go to 16# mainspring and check both single and double action trigger pull, reliability and magazine retention. If all is good, stay with setup. If not go to 18# mainspring and check. In addition, use hard primer ammo (Wolf , etc.) for practice and premium ammo for SD. I'm currently using 90 gr. Gold Dot as SD load. I would welcome your thoughts and recommendations. Thanks.

Thanks. I from what I read, others used a Wolff #16 PPK spring, but the #17 Wolff would be a better choice for me- no modification. That's the first I've read about pierced primers, most posts only mention misfires due to hard primers. I'd appreciate your thoughts on using a heavier recoil spring to reduce felt recoil.

I just read this thread on mainsprings. I changed mine out when I first bought it. I got a 16# spring from Wolff. The deal is, the spring was made for a PP. At the time I got the spring, I did not know they had springs made just for a P-64. Will this damage my gun? What # return spring do I need. Should I change my 16# spring out even though it works fine for me. Don't want to damage my P-64 because I really, really like this little gun. I know I can get good advice form you guys. Thanks

If the 16# PPK hammer spring works in your gun use it . there was some reports of mag drops with the 16#PPK springs
WOLFF just started to make spring for the P-64

herk,
Welcome to the forum, your going to enjoy yourself and learn a lot from the moderators and pick up gems of info from the members, a real good bunch of guys here. I used the 17 lb. Walther hammer spring and the 22lb. P64 recoil, "Soooo sweet". You are not going to believe how accurate your little dynamo is at a distance. You will be equally amazed how fast and accurate double, triple and strings of taps are out to twenty plus feet. Welcome to the club.

I just installed a 22# recoil spring but haven't changed out the mainspring. I'm going to shoot it first and see how it feels. I had trouble getting the slide back on after I put the new recoil spring in so I did what Manicmechanic did and flattened the ends of the spring just a bit and that did the trick. The 17# hammer spring will be next and also the heavier firing pin spring that Wollf sent with the recoil spring.
