Interesting discovery about my Kahr CW45.
I noticed the barrel is marked P45, and has polygonal rifling. This model is supposed to have standard rifling. Did a quick check on Kahr's website, and found the barrel of a CW45 is 3.64", while the P45 is 3.54". This would explain why the muzzle on mine is recessed just a tad into the slide, while the pics of a CW45 show it extended a bit.
Well, no cast boolits for this one. Better lay in a supply of plated.
