I just got back from bass pro. I wanted to buy a holster for my new Colt, but all they had there was a leather bianchi with some kind of 'auto retention' feature that locked into the trigger guard and was released with a little lever. It did seem to work, but added bulk, maybe not such a big deal on an OWB holster. What do you think about these holsters? Should I go back and buy it or buy some other holster online? (my only two options). I'd like to get an IWB too, and I don't have a lot of money to spend.
