I picked this up last weekend for 475.00 and I think it's going to be a range gun that I want to trick out a little. My question to those in the know is, what should I be looking at doing to this gun aside from some real sights? Also what company makes the best fitting parts, or am I fooling myself thinking I won't have to do much fitting. I'm fairly capable with tools but I'm no gunsmith. I would also like to find some good 1911 gunsmithing DVD's to learn as much as I can.
