CM9 recoil spring

[DavidR]

I recall a post from wayback about making one of those nuts out of a regular nut.

Are they not a regular nut?

[Bawanna]

It's a regular nut thread pattern but the hex part of the nut is filed round. Not sure what the size might be. I'd take the part and find a nut that threads on nice.

Pretty sure it was wyntrout that made his own nut, that was quite awhile back.

I had a nut with the proper threads in the garage. Did a little grinding on it, seems to work fine. I think I'll put a new inner spring on before I red Loctite it.

One problem: it's GOLD! Bling my CM9.

[Bawanna]

That works, I like it.

I wish I was affluent enough to buy gold nuts, then grind on them

Wynn posted about making a nut way back yonder sometime....Gold looks good, nice job....My PM9 did the same thing the first time I shot it and I didn't know it was missing until I went to clean it that night..It didn't affect the gun at all, shot 100% first time out and hasn't missed a beat yet...I called Kahr and they sent me a new RSA and so far it's good...Before I installed it I stood it on end and put a small drop of green Loctite retaining compound (strong stuff) on the threads and let it work in over night and it's holding tight...Do call Kahr and get a new assembly for future use, it's a common problem and they will do you right....

Thanks everyone.

I did send an email to Kahr explaining the situation and asking if they would send me a nut. If I don’t hear from them I’ll give them a call.

After I put the new recoil springs in I had to take a little more material off the nut. With the new springs the assembly seems to sit “higher” in the muzzle end and the top of the nut was hanging up on the end of the slide preventing the slide from fully returning to battery. After doing that it seems to be fine when hand cycling so I put some red thread-locker on it and will hopefully range test it next Friday.

Chuck the nut in your drill press, you doo have a drill press, and round it more with a bevel.

And lo and behold look what showed up in today’s mail.
