The French Model 1892 "Lebel" is not a Nagant design, but is in the same class of smaller caliber revolver. It is, incidentally, one of the earliest swing cylinder revolvers, with the cylinder swinging to the right. Some folks say that a cylinder should swing to the right, and that the Colt's leftward swing was due to Sam Colt being left handed (although he had been dead 30 years). Nonsense, of course, and anyone who thinks a right swing would be superior has probably never tried the French revolver.
