I'll have to agree with Sir Knight. I had a Carry 12 and it was a little picky about what it was fed. After I had fired about 300 rounds through mine, I polished the feed throat and haven't had a problem since. The only drawback about carrying the Carry 12 concealed, is the weight. A fully loaded Carry 12 on you hip feels like a brick, even with a good belt and holster.
