Today we are looking at a pair of Steyr 1893 trials revolvers. Only about 100 of these were made, primarily for Austro-Hungarian military trials. These two are early pattern examples, with Pieper-type gas seal systems in which the cylinder is cammed forward upon firing and an extra-long cartridge case bridges the gas between cylinder and barrel. This slightly increases muzzle velocity by eliminating the gas leak at the cylinder gap, but it does so at the cost of extra complexity and a very poor
