if u are referring to a gun to shoot 2" groups at 20 yards. I don't consider any kahr to be that. they can do it but it is a hard gun to shoot that accurate due to the loooong trigger pull If your referring to longevity of the gun being able to take thousands of rounds down range, indeed they are built to take as many rounds as you can give it. they are top quality. they are IMO not a gun to carry often and to shoot seldom. I shoot my G19 far more accurate than my 3 kahrs, but I love to shoot my PM9 far more than my G19 as my PM9 is my 24/7 carry peace and I strive every time I go out to get better with it. but when I want to shoot good groups (for me anyway), I grab my G19 for that. It is also a fun gun to shoot as it has had some serious tuning done to it.
The cw kahrs IMO, you won't shoot them out. they have the finest top quality lothar walther barrels that money can buy, Just look at the upper slide. It is damn near a glock slide, just top quality. Justin moon was an admirer of Gaston Glock and the slide similarities tells alot. The lower grip section is the simplest on the market, just not much down there to go wrong IMO.
Shoot away, these guns can take it, no doubt in my mind...
I think Jfrey and Ripley explained it even better than I did and in less words also..
