Colt's are a problem. I have a pair that I shoot. I really like 'em. But, I shoot 'em. I didn't get them as an investment, I got them to shoot. If I couldn't, or wouldn't shoot them, I'd see very little reason to clutter up the safe with them.
I do admire them. They are so light and quick compared to other pistols we use in our game.
I don't shoot them much, however. The race gunz seem to end up in the car most of the time. And, Colt's are not race guns -- although, you can get them pretty smooth and fast with a little 'smithing.
Personally, I'd take that money and order a pair of hard chrome 38-40s from the custom shop and shoot the heck out of them.
