This is great info!

I had a relative that came from a well to do family and he was a rural deputy in a sheriff's department in Alabama, so he had his choice on any sidearm he wanted. He carried a Blued 3 1/2 inch Model 27 on nice days and a 4 in Model 28 on wet weather days. He wanted to carry his Colt Commander but the sheriff wanted revolvers only. He later went to a model 24 (I think) in 44 Special around 1974. He said the ammo he carried in his 357 was good but seems the 44 special was a better stopper.

He never mentioned ammo preferences, tho.
