Kahr value seems to be a geographic thing. Down here in central Florida they are very hard to sell. Up north around Michigan and the Northeast they are very popular. NYPD bought thousands to issue their officers for off duty carry.
I recently aquired a Kahr MK40 Elite98. The man was asking $600 I traded him a Glock and some ammo, we are both tickled. As you can see, beauty is in the eyes of the beholder. My Kahr has a trigger far better than a stock Glock, is easier to conceal than my Glocks, it feels more solid than my Glocks but you have to give up something it is a little heavier and it carries three rounds less than a .40 Glock. It has become my 24/7 carry piece.
People who really know, not pseudo experts, will tell you that the stainless Kahr models are an expensive, precision made piece and if you buy one plan on keeping it. I plan on passing mine on to my Grandson and it is so well made, he will probably pass it on to his son.
