Just for the records, I am currently shooting Great Western IIs and have been since 2004. I shot Colts up until that time starting in the mid 1980s. I had my picture in the Colt Catalog twice in the 90's because Colt thought it was pretty interesting that I was competing with Colt's manufactured over a hundred years apart One made in 1875 and the other manufactured in 1981. I would still be shooting the Colt's, but the Great Westerns are much prettier and the Munden action jobs on them make them a dream to shoot.
BTW: All my SAs are in .45 Colt
Hope I didn't disappoint you Happy Jack.
