Hello, Just purchased my first Keltec. P3AT with an OD grip frame. Took it apart, gave it a good cleaning. I was a little concerned about the coloration of the bore, but looking at your photos, this is apparently normal. Haven't gone to the range to try it out yet, but If you could give me some pointers, I'd appreciate it. Is there any specific ammo I should use/avoid for break-in? Is 50 rounds enough to ensure reliablity or should I go 100? I will probably get a Hogue handall jr, but what's the preferred grip technique? High thumb or curled down? Thanks!
