Thanks! Really don't know too much more about it. It is a Lew Horton edition, and has a serial number XMD00XX. I have seen several others with different serial number prefixes and rubber factory grips before but not like this one. Like I said, the trigger is AMAZING. Just a touch of the trigger while in single action and it goes. The double action is light and very smooth. I have a set of Hogue's coming soon for it. The wood grips look good but they slip too much in my hands while firing. The rubber ones should help a lot. I was getting 1" groups standing free-handed at 15 yards with it. When I get the rubber grips on I will take it to an outdoor range and really test it out. I was shooting steel rams at 200 yards with my super blackhawk, this should do much better.
