My PM40 has a busted slide return spring, I purchased it six weeks ago and it has 80 rounds through it.
Kahr customer service isn't great so far, can't get through on the phone and all I get is a computer generated reply to my emails

Kahr came through, said they have been short handed and sent me 3 springs, no charge.

How is the Kahr as a shooter? I have been looking at either a PM9 or PM45 for concealed carry. I have experience shooting big and little Glocks, but not Kahrs.

I would classify myself as an intermediate shooter and consistently shoot 8" groups at 25 yards with the little PM40. I think with a little more trigger time the groups will improve.

I have a p9 and it shoots extreamly well. Also is very reliable and has not faild to cycle yet.
