Finally made it to the range to break in the TCP! I brought 100 rounds of FMJ and a box of Hydra-Shok's. I made it through a box of FMJ's with no FTF or FTE, but on the last mag of the first box of FMJ the slide locked back with one round left in the mag. I took it apart, cleaned it, and started on the 2nd box of FMJ. It happened about 5 or 6 more times with both the FMJ and Hydra-Shok's. But, I'm still pretty happy with 120 rounds down the pipe. It is a FUN gun to shoot! Nothing like the P3aT I used to own! I was also pleased with the accuracy at 7 yards, especially with the Hydra-Shok's. I figure I'll give it another 100 rounds of FMJ before I try any mod's to fix the slide locking back with a round still in the mag. Overall I am very happy with this little gun, and hopefully I'll get it right before my CCW comes in the mail. Anyone have any suggestions if it is still doing this after another 100 rounds? I'm hoping I won't have to send it to Miami!
