I once watched an episode of Gunny Ermey’s Lock’n’Load on the History channel where he reviewed the history of the handgun’s development.
In one of the segments he was firing a .500 S&W with the compensated shorter barrel. The moment of firing was recorded in slow motion and I swear it looked like his forearm bones were flexing under the recoil!
That is one hairy handgun!
My brother-in-law and my nephew were standing quite a ways back from me when I fired the 460 Magnum and they said they could actually feel the heat from the round.
My BIL is generous and let me fire the gun quite a few times. The ammo is not cheap.
