I found this colt this weekend and had to have it for $500. The action is tight. Grips have the last 4 ser.# digits with a white marker. I was concerned about the grips at first. The action is so smooth. I saw probably 10 Pythons at this show and several Anacondas. The Pythons started at $1800 and up. I didn't even ask the price of the ones not marked. What do ya'll think.
