Hey, DanM, I've never seen a Ruger flat top .44 mag converted to fast draw or made into a fix sighted gun. Can you post a picture of it? I've seen 357 converted guns and super modified single sixes before, though. Spangenberg's gun shop in Thombstone had a nickel sheriff's model flat top 44 Special for $650 a couple years ago. But a 44 is pretty cool especially if it's still got enough meat in the top strap for full loads. BTW. Your Duke holster is much cooler than the EPSaddelry ones 'cause I don't much like the rolled over lining, tho it's obviously more durable with constant use.
