Despite being abandoned in favour of semi-automatic pistols by almost all military and paramilitary outfits around the world, revolvers have their adherents, usually because they are compact and very nearly foolproof, requiring no complicated safety mechanisms yet are always ready to fire with the pull of the trigger.
Under a barrel
One issue with revolvers is that the barrel of the weapon tends to sit quite high relative to the arm of the person firing it. This causes the gun to tend to twist violently upwards after each shot – the classic muzzle flip.
The Other Way Round
Chiappa Firearms, the makers of the Rhino series of revolvers, have turned this convention literally upside down, so that the barrel lines up with the bottom chamber of the cylinder instead of the top. This lowers the barrel by an inch or so and puts it directly in line with the shooters are, dramatically reducing muzzle flip and perceived recoil.
This is a great application of Principle 13 – The Other Way Round.
