Watch The Gap...on Powerful Revolvers

Make sure you grip big handguns, like this Smith & Wesson Performance Center 460 XVR, the correct way or risk injury.

It's something that's often overlooked in basic firearms training, but there are distinctly different ways of gripping a semi-automatic pistol and a revolver. When it comes to big-bore wheelguns, you must be extra careful and train to grip the gun the right way every time.

Maybe you've been given a vicious warning from a trainer or range officer about keeping your support hand away from the gap at the front of a cylinder on a revolver, especially a large one firing a high-pressure cartridge.

Once when I was at the range with a Smith & Wesson 460 XVR snub-nose, the owner vigorously warned me that the jet of flame exiting the cylinder gap would mangle my hand if it was in the way. After firing a round from that cannon, I certainly didn't want to test his advice.

Unfortunately, it can feel very natural to get a more forward grip on a massive gun like the XVR or a Smith & Wesson 500, especially if you're more used to choking up on a semi-auto. That front-heavy pistol can feel extremely awkward, but respect that big gun and hold it like a revolver!

Luckily, you don't have to accidentally try it one day and potentially lose a finger, because the guys from Mythbusters already did. It's one of their greatest hits, and it uses chicken flesh and bones to replicate a human hand wrapped around a S&W Model 500, one of the biggest daddies of them all.
