Abstract: A projectile in the form of a sabot shotgun slug assembly includes a cylindrical slug, a cylindrical sabot positioned about the slug and a pressure wad co-acting with the slug and the sabot. The cylindrical slug defines a central bore extending partially therethrough. The slug is preferably made of a deformable metal. The sabot defines a plurality of longitudinally extending internal grooves. The pressure wad has two ends, with a gas seal located at a first end and a post located at a second end. The pressure wad further includes shock-absorbing members formed between the gas seal and the post. The post is positioned within the central bore defined by the slug.

Abstract: A projectile having a cylindrical slug with a forward end portion and a rear end portion having substantially the same outer diameter. A sabot surrounds the slug and is nonrotatably connected to the slug so that the rotary motion which is imparted to the sabot by contact between the external surface of the sabot and rifling in a gun barrel is transferred directly to the slug by the nonrotatable connection between the sabot and the slug.

Abstract: A method and apparatus for protecting firearms from dirt and moisture are disclosed. Light-weight plastic covers are used to seal the openings of a firearm such as the muzzle opening or the magazine well opening. These protective covers are easily removable by simple manual operations. This muzzle cover can also be removed by actually firing the firearm, while imparting no significant deflection to the projectile.
