Just picked up a used CW45 today and ran 24 rounds through it to check for function. One round into the 2nd mag I noticed the end of the guide rod sticking out of the frame. I stripped the slide off and noticed that the previous owner had reassembled the recoil spring backwards on the guide rod. Reassembled correctly and no more issues. Goona wring it out this coming Tuesday.
This is not my 1st Kahr, but it is my 1st 45 caliber Kahr. Recoil seems moderate, less than my 3.5 inch Charles Daley. I did have one mag partially eject, but that may have been my fault as I may have hit the button under recoil.
