When the Dirty Harry m29 was on the black market after the movie demanded the craze. I wrote ruger and colt letters about offering a colt Python super sized in 44 mag. As for ruger I suggested a security six on steroids in 44 mag. Colt said they had no intention of offering a 44 mag in there revolvers.
Was at the NRA convention in Milwaukee some years back. Talked to the Colt reps who said they had no intention building a 44 magnum, "The market's already flooded." A year or so later, here came the Anaconda.
As for the new revolvers, I'll be giving the Kimber a hard look. Will I take the plunge? That'll depend on the $$$. What it costs and whether my credit card and I are still friends.
