CM9 dry fire question

[C0untZer0]

When I dry fire my CM9 with no snap cap, the front sight drops down slightly when the trigger breaks - it is very slight but I can see it. No matter how good my grip is and how SLOW SLOW SLOW I press the trigger - there is slight movement and the front sight drops. When I use a snap cap - there is no movement. I am able to get perfect follow-through.

Does anyone know what is going on with this?

I mean besides the striker hitting something like the snap cap faux primer, what would cause this?

The Kahr trigger has a lot of travel (and the grip is short) and you are "rocking" the pistol as you fully depress the trigger through its full travel.

I had the exact same issue with my CM9. Keep practicing (and focusing on the front sight) and you will overcome it. Focus on a consistent and smooth trigger pull rather than a slow one. Squeezing slowly will only exacerbate what you are seeing.

The CM9 can be a surprisingly accurate little pistol.

I couldn't ask for better follow through when I have a snap cap - I just don't understand why it behaves differently with an empty chamber.

Actually now that I've investigated it more, I discovered that when I was using a snap-cap I was also using the magazine - I had the mag in the gun.

I discovered it really isn't the snap cap - it is whether or not a magazine is in the gun.

I'm assuming the mag is pressing up against something and reducing movement.

Well how does it shoot ?? Maybe how well can you shoot it. My cw9 has a little wiggle but still good for ragged 2 1/2" holes with a mag full at 10 yard groups. That's fine with my eyes. The mag spring just takes up what little slack it has and a small pistol most have some to be reliable. Go shoot it.

Mine does that, when you start pulling the trigger it pushes the slide up a little then when it breaks it drops down, probably don't do it at all when firing a live round. My CM9 is very accurate.

Movement of the slide, as you described, it pretty much the norm for a striker fired pistol.

 

[C0untZer0]

It is accurate enough, this is 10 rounds at 21 feet, and 7 rounds basically made 1 hole, the shot group is about 1.75" At 50 feet I am able to create 3.5" shot groups. I'm happy with the accuracy, it is just that the dry firing was something I couldn't figure out.

Ive read that this is normal for Kahrs. My CM9 dips as well. None of my Glocks do it, neither does my Walther. It's a Kahr thing.

It is actually a long trigger travel thing. You may try putting a bit more finger on the trigger. That works for DA revolver shooters and may help with your Kahr.

I'm afraid not; the issue being discussed has absolutely nothing to do with trigger control or pad placement at all. The slides on these guns physically drop when you pull the trigger on an empty chamber. You can put the gun in a vice and you will still see the same thing. It's a pretty well documented Kahr thing.

Boricua So what. They shoot well and are more than accurate enough and does not seem to bother anyone but a few newbe's and a few anal folks.

You don't have to tell me; I love mine so far! It's accurate, reliable, and nicely sized between a doublestack sub-compact and a mousegun. That said, mine doesn't break followers or have any problems loading whether I'm using the slide release or slingshotting it.

The point of my post is that this is a physical thing that actually happens on these pistols. Everyone is always quick to come in and blame people of having poor form, poor trigger control, etc. when in fact there is a mechanical reason behind what is being observed.

Thanks boricua9mm,

I should have posed the question on KahrTalk, but there are so many experts here and the responses are pretty fast - comparatively.

Thanks for chasing down those KahrTalk threads.

I shot my CM9 today and it is accurate enough, it was just that the dry firing was driving me nuts!

And I really love dry firing.

So anyway, now when I dry-fire it I use a Snap-Cap with the magazine inserted so I can get that feeling of satisfaction of having perfect follow-through
