A few years ago, all the gun writers were moaning and groaning that you just didn't get magnum velocities if you used a barrel length less than 6-inches, and 3-inchers were just a waste of time and money, they said. Meanwhile, on the streets the bad guys were dropping no matter what the barrel length.
I've seen 4-inch guns get higher velocities than 6-inchers just because the tolerances on the 6-inch were a little different. And 3-inch magnums were doing an exemplary job putting down bad guys and, at closer ranges, deer. You'd never want to be on the inside of a car with any cartridge, especially not a .357, and the muzzle blast from the shorter tubes is nothing short of a flame thrower.
People talk about how much hotter the .357s were, but honestly, I think modern pressures are better. They're not only easier on the guns and the shooters, they retain more than enough power to cut through cars, vans and people. It's equally at home on the streets as in the field. Heavier bullets give greater penetration, while lighter bullets are devastating to man-sized targets.
It's not for pantywaists, but if you can get a shot to connect, you'll often not have to worry about getting off another. It's probably not the best thing to use in a home or condo, but for camping and hiking, it's hart to beat.
It's the one round that autoloader manufacturers try to duplicate, but so far they just haven't found the magic "bullet."
Even short barrels deliver devastating blows.
