Hiya Waldo,
I had it converted a few days after I bought it --- it was around 1990 or a few years earlier ----- in the almost 20 years that I've been useing it in competition { IPSC , IDPA , Bowling Pins , and Steel Challenge etc.} it is still "freaky" accurate !!! I really do not know how many rounds I've shot thru it , more then 25,000 and maybe as high as 50,000 !!!
I first used it for IPSC and as that it a fast game , I feel there is really no place for thumbing the hammer for single action ---- I have hit steel " Pepper Poppers " out to 100 yards with this gun in DAO. ----- Last year I put a Hi-Vis red fiber front sight on it --- after turning 50 years old , my eyes aren't as good as they once were.
I also have one of the first year stainless Colt Delta Elites ---- Around the same time , I had it built into a full IPSC "race gun".
Right now , my favorite 10mm auto is my EAA Witness Elite Match --- WAY MORE accurate then the Colt Gold Cup Delta Elite I had.
