I recently bought a 905 Instant Backup. It was nice to look at, but not very reliable. I put 100 rounds through it, but the cylinder would bind periodically. This would lock the gun up for periods of time. It would then start shooting again. It did not seem to be related to a specific type of ammo. It could be that the tolerances were too tight, but I would could also feel this bind every now and then when dry firing. This led me to believe that it was something else. I thought about sending it back to Taurus, but (from multiple experiences) I did not like the idea of waiting 4 to 6 weeks minimum to shoot my brand new revolver. I have owned 7 Taurus firearms. My 605 was great as was a 94, but the 85, one of my CIA models, the PT 111 and my most recent 905 purchase, required (or would have required in the case of the 905) a trip back to the factory at least once. So, buy at your own risk, Taurus seems to be a crap shoot. I traded my 905 in on a S&W 642. That said, I'm not reading rave reviews on S&W either, but if I had to chose between the two, it would be a Smith. I'm not saying that Taurus doesn't make a decent gun, just sharing my experience. Many seem to like Taurus. I was once a fan myself.
