I had a Kahr P45, the upgraded CW/CM45. I intended to make it my carry piece, but it had some ignition problems (that I traced to what I believe was a short chamber.) I also found it didn't fit my hand as well as the CW9 I was already carrying... so I just stuck with that and traded the P45 off... for another CW9.
When it did fire, it was accurate as all get out, and I didn't think the recoil was that bad vs my 4" 1911, even considering the lighter weight.
On the downside... both of my .45 magazines cracked at the top, on the back of the spine at the weld, so I would keep an eye on that. The mag will be difficult to insert into the pistol, and not drop free when you punch it out.
