I love mine. I followed Jocko's advice for break-in, and not one failure to feed or failure to eject with five out of six types of ammo so far. Loves Federal FMJ, Remington JHP, LAWMAN FMJ, Speer Gold Dot, Hornady Critical Defense, Hornady Zombie, and Corbon Pow'r Ball. Doesn't like to load WWinchester PDX, due to the ridges at the front of the bullet. Even though Kahr says it won't load a round if you "slingshot" the slide, mine will. It's a black one without night sights (the LGS did not have the black version with night sights when I bought it). I plan to purchase the XS night sights for it. It is the one I choose to take, over My Glock 33, due to the ease of which you can pocket carry it. I recommend the holster from pocketholsters.com. Awesome. Looks like a wallet to everyone else.
Oh yeah. It's also fun to shoot at the range. I am as accurate with it as my Glock 33.
I miscounted. I guess it loves 7 out of 8 types of ammo.
