The Unofficial P64 Resource Forum

So I've got 2 P64s, and I put wolff hammer springs in both of them with no problems. I've toyed around with a few different springs back there without any issue on either. I also snagged the pack of (20#, 22#, and 18#) slide springs as well. I put the 22# in one of the guns to see how it felt and it went in just fine. Little bit heavier to pull back on the slide to get it re-seated, but it seated just fine.

On the other one, though, the slide spring it came with is a bit shorter and the slide can't be reinstalled with any of the three wolff springs in there. The spring prevents the slide from making it back far enough to engage all the way down. Anyone else ever seen a P64 that uses a slightly shorter slide spring? Seems like an odd one, I'll share more details on request. If I recall correctly, both guns are circa '68.

Thanks!

Be interested in what everyone says.

Does the stock recoil spring of the other gun fit?

Did you grind the ends of the new springs flat like the original ones? Wolff should do it but, alas, they don't. Look at the 18# OEM springs that came in the gun and you'll see what I'm talking about. The ends of the new spring(s) MUST be ground flat so as to work properly. I think that may solve your problem, length of spring notwithstanding. I think you might've been lucky with the first one. I'd grind both springs to be sure....

I think you might be right here. I did notice that they were flat on the stock springs, but I had never seen any documentation that this would need to be done on the wolff springs so I didn't think of that.

What's the best way to grind them? Never done that before, so not sure what the best method is.

Thanks!

Something that you need to note when putting these springs on; The replacement springs don't match exactly the factory originals. The originals are flattened at the ends, where the replacements are not. Some people don't have a problem with this. But for most of us it will cause the slide to bind. Refer to this thread to match the ends:

Do NOT try to put the slide on if it does not seem like it wants to!!

If you can get to a bench grinder that would be easiest. Dremel second. Some kind of electric grinder is the best. Used a Dremel on a few and got access to a friend's bench grinder for the others and THAT was best, fastest and easiest, hands down. Doesn't take much, just get that first coil, both ends, flat. DONE!

Slick! Time to go find some wood, a nail, and some sandpaper.

I had this exact same problem with the Wolff spring, and this was back in July. Folks say it's been an issue longer than that. You'd think Wolff would start shipping the springs pre-flattened.

Thanks!
