Can't speak on the Kahr CW9. I owned the smaller Kahr CM9 before I returned to Kahr for a full refund due to the front factory installed night sight breaking off twice.

I now own a Shield and from my experience Kahr has one thing on my Shield-the trigger but not enough to make up for the inferior magazine.

It is beyond me why Kahr would build a decent weapon and finish it off with an awful magazine that requires the owner to constantly tinker with it to ensure the rounds properly feed.

No joke if you search the official Kahr gun forum there are posts of owners sanding/grinding the magazine and/or polymer to ensure proper fit or squeezing the magazine sides in a vise.

I will admit I did all of the above except sand the polymer.

Personally, I don't think it speaks well of the Kahr's workmanship if sanding and squeezing is required for the magazine to drop from the well.
