That's because the .357mag is primarily a revolver caliber and with their high bore axis and inverted cone shaped grip, a revolver is far more difficult to shoot accurately rapidly than a semi-auto is.
I just love these all inclusive blanket statements...
.357 primarily a revolver round? yes, but I have two different .357 semi auto pistols... cone shaped grip? ok, but grips can be changed...
Far more difficult to shoot a revolver accurately and rapidly than a semi auto??
WHICH ONES???
They aren't all the same, and different guns and calibers makes just a tiny bit of difference!
Clearly, you have never shot a 9mm Bolo Broomhandle Mauser..
As to the pistol caliber I went back to, that would be .357 Magnum. I have lots of others, but that one was the only one I'd ever left. Somewhere around 30 years ago I sold my Model 19 and was "done" with the .357. I had guns on both sides, so I figured I just didn't need the .357 any more.
That lasted 2 or three years, until I saw an unfired, in the box Model 28 6". My Dad had a 6" 28, that was the gun I learned .357 on, and well, you know, I just had to have it. I actually lasted almost 10months before I broke down and shot it, and damn glad I did.
No safe queen now, it came with the target hammer and trigger installed and it now wears pachmayr grips, and is my favorite DA revolver.
