I am experiencing a new problem on a contender pistol. I sent the frame off to TC for repair for a reoccurring loose firing pin plate cover. I believe TC replaced several parts. My new problem is that when firing the pistol with a 44 mag barrel, the firing pin selector moves from centerfire to the no fire position following every shot. With a milder recoiling barrel (22 LR) this does not happen. Any one have any ideas? I know if I send it to TC they would fix it for free, but I hate to do without it for the 3 to 4 weeks it would take, plus shipping it is a hassle. Thanks.
