The "ordinary" DAs (not Redhawks etc.) are also much easier to carry than the big SAs. Had a 5 1/2" Bisley that was very nice, but carried like an anvil. All that steel in the grip didn't help the balance either. I always chuckle a bit when I read about the use of the big SAs as bear protection. They've got the power, no doubt, but pulling that big iron out and thumbing the hammer with 500 lbs of irate bruin sitting on you has got to be tough. Like to see one of the shooting schools come up with a drill for that situation; maybe a nail-studded round bale rolled over the student.
These days, I carry a 7-shot .357 L frame, which is plenty for anything hereabouts, and carries easy. The DA pull is smooth, and the SA pull just "goes" with no perceptable movement. The Mountain guns are really nice, but opportunity and resources haven't synced for me as yet. A .45 would be perfect, as I keep a bunch of bullets around for my inline anyway.
