That is a great price for NIB. They usually run around $325-350 in my AO. I have owned multiple Kahrs over the years and currently have a CM 9, and a CW 45. The ONLY problem I have ever had with a Kahr was with one of my 45 mags. It developed a split at the top left rear corner, right in the fold. It was obviously a little too thin when it was made. Called Kahr and they sent me 2 mags as replacement.
IMHO most people who bitch and moan about the triggers have never actually shot one, TOTALLY MISUNDERSTAND the design concept behind it, or have not/will not take the time to train adequately with it.
The guns were designed from the beginning to mimic a DOUBLE ACTION REVOLVER as to the trigger function. With no external safeties, the longer trigger pull is in essence a safety of a sort by requiring a steady, positive, and determined trigger pull. The design works very well. Personally I prefer the Kahr trigger to all of the factory Glock, S&W, Springfield polymer triggers I've shot. They are smooth without all the glitchiness the other guns seem to be cursed with.
Why do you not see aftermarket triggers for the Kahr pistol? Simple. They're not needed. What is needed is for you to buy the gun and then actually take it to the range and shoot the goddam thing enough to be COMPETENT WITH IT. The same as you would do with an actual DA revolver, or any other pistol for that matter.
So yes the gun does have a bit of a learning curve that is different than a lot of other pistols out there. But for those willing to take the time and learn the gun and practice with it, you will have a very reliable, accurate self defense concealed carry gun you can depend on. And do so at a very reasonable price.
