I got my wife and I each a new Kel-Tec P-3AT a couple of weeks ago for EDC concealed carry. Cheaper Than Dirt Outdoor Adventures had a sale - $249 with a 50 round box of ammo. Not bad since a box of ammo is going for over $30 now-a-days. Ordered Crimson Trace LG-430 Lasers and we were all set. Went to the range Saturday and began to shoot and adjust the lasers on each. Just as soon as I got both pistols sighted in and we were starting to enjoy shooting them, about 50-75 rounds into it, each began to double feed at least once on every magazine. Is this the break-in malfunctioning I heard about and will go away or is it something more serious? Before even going to the range I broke down both guns and cleaned and lubed them. These are not our first handguns. We were not limp-wristing or anything. All of the ammo was Winchester (white box) 92 gr FMJ brass case ammo. Should I be concearned or just shoot through it and worry about it only if it doesn't go away after 250 rounds or so? As it stands they each have about 100 rounds through them.
