…the most powerful production revolver in the world anyway, and that’s just according to the manufacturer. For whatever reason, Russian designers took to creating a revolver to fire their 12.7x55mm cartridge (speculated to be a cut-down .338 Lapua case…), it has been suggested for the purpose of destroying locks and other objects.

Holding a firearm is like holding a lever from a physics pov. It takes less force if you apply it higher up to let the muzzle climb. A low bore axis handgun doesn’t eliminate the force but sends it into the shooter rather than using it to flip the muzzle. Keeping your sights on your target.
Physicists feel free to correct me if I screwed this up. Think it’d be a class 3.
