The questionable things I've heard on Taurus were all semi's, not a revolver. I have a 605 and a 617, no problems, love shooting both and very accurate. I also have some Smiths, but it's the Taurus 617 that I carry. The other carry is a Beretta PX4-SC. I've never had nor heard of a problem yet with either a 605 or a 617 Taurus revolver, nor the 618 (8 shot).
IF someone has direct knowledge, I would like them to post the specifics... and I'll bet you wont' see a post.
