Wondering if anyone has ever seen this? I have a 239 in 40 and a .357 conversion barrel. I’ve shot close to 1k if .357 through it without an issue. Last night while shooting, I finished a mag and went to reload. When I went to hit the slide release, nothing happened. Upon further inspection, there was no spring tension on the slide. I took the gun apart and the recoil spring was gone! I carry a spare in the case. When I went to put it in, the recess where the spring stops in the slide is gone! The spring just slides all the way through to the muzzle. There’s a sharp edge all around the circumference of where the guide rod hole is/was. The hole now is big enough for the spring to come all the way through. I bought it new in 2011 and the gun has close to 2k rounds on it. I’m pretty confused on what could have happened and am trying to wrap my head around it. Thanks

A photograph or two would be interesting.
(Assuming I understand what happened, I have never heard of such a failure.)

Added photos in original post

My thoughts are that the recoil spring was too weak and eventually went to full compression and punched through the slide nose. Or maybe a stress riser from milling. Either way, metal fatigue took its toll.

It was a new recoil spring with about 25 rnds.on it. Appreciate the reply

Thanks for the photos.
That is bizarre, and as I say, nothing I’ve ever even heard of before. I assume that the part that disappeared from the slide was welded in place, but not properly. Or perhaps not.

Hopefully SIG will take care of you, although as the P239 has been discontinued ….
Please keep us posted.

I’m hoping they get that repaired for you.

Does Sig spec the same recoil spring for both calibers?

There are different recoil springs for the 9 and the .40/.357

The fix for that is probably going to be a reverse plug like many full length guide rods use on 1911's.

Well, that particular location of metal failure on a SIG P series is a first for me, as I've never seen it discussed on the forum before.

If you purchased the gun new in 2011 then it should be covered by SIG's lifetime warranty, so please follow-up and let us know what their response is.

I have an update to the problem I had. I contacted Sig’s customer service and dealt with a guy named Bo. I explained the problem and he issued me a RMA number and a shipping label.
Sig received my package on Monday the 21st. I was holding it in my hands this afternoon,the 24th!
The slide was replaced with my night sights transferred, both barrels(.40 and.357) I sent with the gun were test fired. Simply incredible! There was no indication on the worksheet as to why the problem occurred.
This was my first time ever having to send a gun back and was a little nervous since the 239 hasn’t been made for awhile.
Thanks to Bo at Sig customer service and the techs who fixed it up!

Very good!
Thanks for the update.
