CM9 Slide Stop loose

[swolf74]

I just noticed today that the slide stop on my CM9 is a bit loose and can be moved slightly up and down with the slide forward. Not sure if this happened before. Perhaps I'm just a bit paranoid because of other problems (broken mag follower, rusty mag catch). Does anyone know if this is normal, or do I need a new slide stop spring? I have about 350 rounds through it, and it functions fine.

The stop should have some spring tension holding it down. If there isn't any then perhaps the spring is positioned below the stop, bent, loose, or has rotated out of position.
You might pull the stop and give the spring a look. If it looks good, then install again with extra attention to getting the stop's tab under the spring. Here's a photo of a good and correctly positioned spring:

The spring looks identical to what you have pictured. I removed the stop and installed it into the frame without the slide and the spring does indeed position itself below the stop, snaps right in. Not much tension though - when I push it up with my thumb, it stays up:

How do I attach a photo?

With the slide off and the stop/pin through the frame, it does in fact spring back down, but it doesn't do that with the slide on.

I just checked mine - it does the same thing. It functions fine. Has 600+ rounds through it.

Okay, thanks guys. I appreciate the help.

Here's a better look at what's going on:

Yep - that's exactly what mine does. Hopefully one of the experts will come along and tell us it's fine, shoot it like you stole it.

Right on...

The motion looks normal to me. The slide stop spring holds the slide stop down with a little tension. When the mag follower gets to the top of the mag the little metal tab on the follower pushes the slide stop up to latch the slide open on the last round.

The thing is, it doesn't hold it down - when I push it up, it stays up. It probably won't affect function, just want to be sure.

I went ahead and ordered a new slide stop spring. Will post results. Thanks.

Just checked mine. It also has a little movement. 2500 rounds and going strong. Shoot it.

Are you putting the little tab on the slide stop UNDER the spring? This video http://www.kahr.com/p9-takedown.asp goes into some detail about it. Theres also a sticky somewhere in the proper prep section that addresses installing and torquing the spring screw.

Yes - I made sure of this by removing the slide and reinserting the slide stop into the frame so I can see it snap right in under the spring. Thanks for your reply. I appreciate it.

Guess I'll just have to put a couple hundred (or thousand) more rounds through it. Thanks...

With an empty magazine in place there is no movement of the slide stop. With the magazine removed the slide stop will move just as pictured in the video. That is perfectly normal. If the slide stop moves with the empty magazine in place you have a problem.

Okay, I just tried it. The slide stop doesn't move at all with an empty magazine. Thanks for the help.

I'm not totally on board that the stop is "perfectly normal" as pictured in the video.

In the video, it appears that the stop, after being pushed up, is staying there until forced back down by the operator.

How much of issue is it? Well, as the OP states "I have about 350 rounds through it, and it functions fine" my only question would be: Has the OP tried to "slingshot the slide" during those 350 rounds? If so, then it's no issue at all.

Perhaps a drop of lube is all that's required to keep the slide stop from sticking in the up position.

I agree:)

I only release the slide forward by using the slide stop. Isn't this what Kahr recommends?

I tried a bit more lube on the "round part" of the slide stop with the same result.

Thanks.

Actually, I have tried this, and the slide stop drops down as it should, allowing the slide to move forward, but only with the gun empty during cleaning. Is this what you mean?

That is what Kahr recommends for their pistols, but with proper technique, you can chamber rounds in them using the "sling shot" method.

If "the slide stop drops down as it should, allowing the slide to move forward" when the gun is empty (no magazine in place), it should do so with a magazine in place that contains some ammo.
I'd say your slide stop is functional as is.

I loaded a magazine with snap caps and cycled through it by using the sling shot method and it works great. I guess there's only one thing left to do...

Thanks for the help.

That's good to hear. I'm planning on putting at least 100 rounds through it this week. It really is perfect, especially for this time of year.
