I just bought a used Taurus Titanium in 45 Colt today and I don't know what model it is. There is no model # on the gun. I have looked at pictures of Taurus revolvers on Gun Broker and it looks like a model 85 except for the grips. It also looks like a model 450, even the grips. The one difference I did notice from the 450 is that the 450 had an SL prefix before the serial # and mine has an SH. No big deal anyway but I would like to know the model. Does anyone know how I can positively identify this gun and maybe have any experience with the Taurus Titanium?
