Abstract From the Canadian patent
The present invention relates to a caliber reducer for hand weapons. The caliber reducer comprises a caliber reducing tube with a bore, the axis of which is situated in the barrel bore diametral plane passing by the line of sight of the weapon. The reducing tube bore axis diverges relative to the barrel axis in the direction of the muzzle. The object of the invention is to preserve the holding of the weapon despite the suppression of the kick due to the reduced caliber, by compensating for the divergence of the line of sight.
