The 20-inch barrel makes the Guide Gun compact and nimble. These are wonderful qualities in any hunting rifle, especially when shots might need to be taken under stressful and unanticipated circumstances, as can happen while stomping through grizzly country. But they come at a price.
Taming the Beast**
My rifle weighed 8 pounds 2 ounces unscoped, which isn't much when you're trying to handle the recoil generated by the .375 Ruger's 4,835 foot-pounds of muzzle energy with 270-grain loads. To mitigate that, the Guide Gun comes with a removable muzzle brake that takes some of the sting out of the kick, though you'd better be wearing excellent ear protection when you pull the trigger.
