HIGHLY RECOMMEND the Ruger Redhawk, stainless, 5.5".
Mine wears Pachmayr Decelerator grips, and a Millett orange-ramp front sight blade.
Strong. Accurate. Handy (although Bowen, Stroh, Magna-Port etc. can cut you back to 4").
Own four Redhawks, one in each caliber, all awesome. But if I had to leave three behind I'd keep the 45 Colt....
.....and the ammo I make in 45 Colt is awesome, too.....
