I have a CM9, it's not quite a pocket pistol for me but is smaller than most of the other pistols in its class. The CW380 is actually smaller than the CT380 and is truly one of the smallest 380 pocket pistols made.
I'm not some Kahr fanboy, they just make a pistol that fits the classes of concealed carry guns better than anyone else in my opinion. My CM9 has been completely reliable in the past few years that I have owned it. I don't shoot it much but I fired about a thousand rounds thru it just to prove that it is reliable and I have found it really is.
I am planning to add a CW380 as a pocket pistol at some point to my very small, just one right now, concealed carry cache and that would probably be the last one.
Many know that I'm a range shooter that likes shooting with large frame guns as fast and as accurately as I can. So these little bitty pistols don't make my life by any means.
