Easy and quick to reload and half the price of 38s to shoot. For someone that enjoys revolvers it is a Win/Win. And, it allows for Ammo consolidation.
Still, there is NOTHING wrong with a S&W Model 625 or older flavor, and anyone with 1911s would be remiss without a revolver in .45 ACP. Additionally, no collection would be complete without at least one variety of .357 double-action revolver. But, a 9mm is quite sweet!
