Can't get slide on with Wolff recoil springs

Post by Esquilax » June 27th, 2018, 1:04 am

Hi, I just joined. I did a search, but didn't find a definitive answer.

I got the recoil pack from Wolff. Whether trying the 20 or 22 pound recoil spring (one that goes around the barrel), I cannot get the slide back on. I can pull it back all the way and down (with more effort than the original spring), but instead of returning straight forward the back end flips up slightly and the entire thing doesn't get seated.

I found some very old discussion that the spring needs to be modified, is that still the case? This website (main website, not forum) just says that people were modding HK P7 springs before Wolff came out with the P64 specific.

Also, I put the 18 pound hammer spring on, and the new firing pin spring. Assuming I can get either recoil spring to work, what should I look for to see which is better?

Are you sure you have the trigger guard pulled out of the way?

Also, do you have the recoil spring flipped the right way? The narrow end goes over the barrel by the breech.

Yes and yes! Will try to flip it just in case I'm looking at the width wrong. I tried it with the original spring and it works fine.

Welcome to the forum and yes I would modify the spring.

Thanks. Is there a guide anywhere, or how much? A few mm, or a whole rotation of the coil?
I will contact Wolff too and post what they say.

Still waiting to hear back. I did some more searching and found this thread here, with helpful pics, though again it is from 7.5 years ago. But I assume not much has changed?

Is the muzzle end of the spring round or flat? It needs to be flat as the heavier springs seem to be of a mite thicker diameter wire and are therefore a bit longer. Flattening it with a piece of sandpaper will do the trick.

Like Curly said, that thread is a good one to follow. This is still a common problem, not sure why no one pointed you at it sooner. As you can see from previous discussion; if your Slide doesn't want to got on with the Wolff spring installed do NOT force it. It will be a pain to remove. You'll need to fix the ends of the springs in the manner shown in that thread.
