*I know they now make semi-autos that shoot .357, but I'm ignoring their existence as I believe using a round designed for use in revolvers in a semi-auto is a bad idea, and also somewhat dangerous, as the bullets aren't crimped into the brass and are apt to move in the magazine due to the force of recoil, and you end up with more space in the case, which changes the pressure, changes in head space which can cause feeding problems, and messes with accuracy, or you might even have a bullet fall out.
I don't intend to be rude or contrary, but all of this is incorrect. The bullets
are crimped, if one sees fit to do so. The cartridge head spaces on the rim just as in a revolver. In an auto-loader, the recoil pushes the frame and magazine against the bullets, causing them to enter the case further,
reducing interior volume and increasing pressure. There is a chance one could spontaneously disassemble a pistol, but the bullet will not fall out. The only bad thing, that I can personally think of, is that a Coonan three fifty seven is nearly twenty three hundred dollars.
Oh, but I want one. I want one very badly. (sigh).... Someday.
I do suppose that a misloaded magazine could cause feeding problems, if one rim was loaded behind instead of in front of the preceding one.
I chose nine millimeter and fourty-five auto. I have one nine. It is a fine firearm. Good for the house, with a light on it.
I love nineteen elevens. I have a few. I love the fourty-five auto. Easy shooting or Thor's hammer in one cartridge. With over a hundred years of customizing and improving what's not to like? Springfield Xd are fine firearms too.
Though I don't have any experience with a Fourty Smith and Wesson, yet, I think I will try thirty eight Super next.
