I'm 64 now, but as a young man I aways wanted a Colt with a 5 1/2" barrel. This was not because of any preference or use, but because Colt always advertised it with a picuture of a 5 1/2" barrel. (Yes, Colt used to advertise!) It was just a case of familuarity. When I began to use single actions, my first Ruger was a 4 5/8" barrel, followed by a Super Blackhawk with a 7 1/2". One seemed to work for me as well as the other. In years past, I gravitated to the 4 3/4" barrel on Colt's that I owned. Now, I find my belt guns are all back to 5 1/2" and seem no less handy than the shorter barrel length. I still have a wish to build a .44 spl round butt on the 'New Vaquero' frame with a 3 1/2" or 4" barrel. I've had two custom builds with 4" barrels and you would be amazed how nicely they balance. A little off topic but just my preferences. 44 Man
