when I read the page on their site. Complained about "feeling" the slide go into battery as with a weakened spring. Since this was my 2nd replacement after only 1500 rounds, I was set to complain.
The customer service person indicated that Kahr had redesigned the recoil spring set and sent me an example of the new set, gratis.
Now that I know the spring is fixed, I need to send my barrel in for "r or r". Good news and bad.
