I received a Taurus PT 1911 in trade yesterday from my brother. I love the guy but hes not good with his guns. The slide is a little worn and I'm just not fond of the aluminum frames color. I would like to refinish the entire thing black. Anyone know of a good product to use to do it or maybe a good place to send it in and have it done? Also curious about what it may cost because Bob at plainfield shooting supplies offered me $450 trade for it and if its cheaper I'll just trade it in for a different color and a steel frame. Thanks in advance!
