No mag sticking issue.

[Conceal155]

Just picked up my CM9 today. I read several others addressing the magazine sticking issue. I wanted to see that the moment I picked it up at the gun shop. No issue with it sticking at all. The only thing I noticed was depending on how I held the gun, sometimes the mag would hit my palm stopping it from ejecting properly. Other than that, the mag slips right out with no issue. I took it apart and that is a little challenge I guess cause the gun is new to me, but I had it apart and lubed it up and immediately noticed a difference in pulling the slide back once I put it back together. The slide release is a little tough on the hand but hopefully will also improve once the gun is broken in a little. That said, I can't wait to start shooting it and getting it broken in.

... but hopefully will also improve once the gun is broken in a little...

Yep. It just gets better and better. Welcome.

Mine has smoothed out considerably after about 230 rounds. Have you checked the firing pin channel for debris?

Why would I check the firing pin for debris?

It seems that they come from the factory with a free quantity of junk in the firing pin area. Mine had just a little.

I think that generally this is much better now days. It used to be more of an issue years ago.
Based on that information I have checked mine before shooting them just to see what if I had any and mine (3 plus a couple friends) were pristine. Oiled and pretty but no extra junk.

I suspect it still happens and if one takes the top end down for a spring replacement or whatever I'd certainly check and clean accordingly. I just don't think it's as common these days.

I polish my magazines inside and out. I'm OCD that way but it makes the mag buttery smooth.

[Bawanna]

I don't do the inside but I do polish the outside. Not sure what OCD is but I probably got that too.

I like smooth.

I found some small metal shavings in mine. Never hurts to look.

Thanks for the info. Mine was clean also.

Yep not a problem with new mags and weapon. I concluded the same and that was people who were complaining about sticky mags were obstructing the other side of mag release.
