Always wanted a Ruger SA and having followed this forum for some time am getting closer to taking the plunge. I was originally focused on .44 magnum, but have decided to go with .45 Colt/.45 APC convertible instead. After getting past the choice of caliber issue, I'm now struggling with barrel length. Inclined to go 5 1/2", but some of you have said the shorter barrel balances much better in the .45 BH. Not particularly concerned with loss of MV in the shorter version. What should I have in mind when I get to the LGS and actually handle the two barrel lengths? Or is it a big deal one way or other?
