As mentioned in another thread, I'm a new member here who purchased the P-3AT in part from the good info I got here. Mine apparently is one of the newer ones (JSZxx range) that has the newer trigger and has the 'carved' ramp. So other than giving it a good cleaning and a bit of buffing on the ramp, I have not made any other changes. I had initially fired just a few rounds as soon as I got it just to get a general idea of the feel. But now I was ready to go and see how it handled a whole box. For comparisons, I took my AMT 380 backup (which is too heavy IMO and one of the main reasons I wanted to get the Kel-Tec). I live on 50 acres out in the middle of nowhere (Texas), so I don't have to go to a range. So I ran 50 rounds through each. Mostly in rapid fire. Neither had any failures (using American Eagle 95gr ammo). Both had equally good groupings, but there is no doubt that the P-3AT has a lot more recoil. Of course I realize that it's light weight and the slimmer size plays a big part. But I was pretty surprised at the difference. The Kel-Tec is not something I would fire for hours at a time. But the bottom line is it does what it needs to, does it well, and will make a nice replacement for the AMT. BTW, I also own a Beretta 92FS and a CZ85 both which I love to shoot.
