I believe I saw it on The Firearm Blog a few months ago.  I even commented on the post.  It was an article and range review of a single stack 9MM striker fire gun that takes 9mm 1911 mags.  The model had the number 10 at the end, which confused people because they thought it was a 10mm, but it was referencing capacity. It was a slim Commander-sized carry gun, but the only 1911 commonality was the mags.  

Any help is appreciated.  Thanks!

Interesting.

Yeah, I remember that article now.  Odd place for that rail to stop<img src=http://www.ar15.com/images/smilies/smiley_freak.gif border=0 align=middle>  Also still at 1" wide with only 10rds on tap I'd still pass.  At .90 or less, then it makes sense.  I think Kahr already did this gun, but maybe better.  It is definitely slimmer.

Kahr does beat it on the price point, unless MSRP turns out to be just that, a suggestion.  If the new gun is 10+1 or 11+1, then that goes to it, along with the trigger being a striker fired instead of DAO, which is a huge reason more people like the 320 than the 250, so we'll have to wait and see.

Thank you!!

Kahr is striker fired
