Sixgun Nut
I wouldn't lend much creedence to such statements. GP's and L-frames are considered hell for stout for .357's and a Colt SAA-sized single action in that chambering is head and shoulders above either for strength and robustness.The idea of shooting a NM Vaquero or Italian clone loose with a steady diet of full house .357's isn't mine.
Conversely, I don't find any centerfire as easy to load and unload as an Old Model Single Six. I hold the sixgun in my right hand and load with the left. All I do is grab five rounds from a bulk box and drop them into the loading port one at a time as I turn the cylinder with my right thumb. I don't deliberately insert them into each chamber. I let gravity do the work.The issue of loading and ejecting 9's in a SAA style gun is my own feeling based on the fact that I do find loading my Ruger Single Six with .22's to be a touch "fiddly" compared to loading the much longer and easier to handle .38's in my Pietta SAA's.
Ejection with 9mm's will also be much, much quicker, easier and more positive.
