A magazine for rimmed cartridges includes a magazine tube having first left and right ribs on an inside of the magazine tube extend inward from a forward portion of opposite sidewalls and are laterally spaced by a first spacing. Second left and right ribs on an inside of the magazine tube extend inward from a rear portion of opposite sidewalls and are laterally spaced by a second spacing that is greater than the first spacing. When the magazine is filled to capacity with rimmed cartridges, cartridges in the magazine are arranged in two offset columns with projectiles of the rimmed cartridges laterally spaced from a median plane by a first distance and rims of the rimmed cartridges laterally spaced from the median plane by a second distance that is greater than the first distance. Also disclosed is a baseplate that attaches to a magazine tube using a snap fit.

An apparatus and method for a slotted trigger actuation mechanism for a firearm are described herein. The slotted trigger actuation mechanism may be a slotted trigger bar interface. The slotted trigger bar interface may serve to increase a distance of trigger pull required to execute firing ammunition. A trigger body may comprise a trigger bias for increasing trigger work. The apparatus and method described herein may help to improve results during drop safety testing.

A firearm slide includes a mounting plate that is removably connected to a planar mounting surface of the firearm slide. A rear sight is removably attached to the mounting plate so that different types or styles of rear sights may be used with the firearm. Upon removing the mounting plate itself, various mounting features defined in the planar mounting surface of the slide are exposed. These mounting features can be used to attach any of a variety of accessories (whether a telescopic sight, a red dot sight, a light, or other accessory) directly to the exposed planar mounting surface of the slide.

Firearm slide

A method and for mounting a flat printing plate on a cantilevered plate cylinder of a printing press, particularly in a lithographic web-fed rotary printing press. The printing plate is bent into an essentially cylindrical shape and inserted into a hollow tube. The tube and plate are slid from the side over a mandrel mounted on the plate cylinder. The mandrel expands the printing plate to a condition where the mandrel has an outer diameter which is smaller than the inner diameter of the tube and which is larger than the outer diameter of the plate cylinder. The tube and printing plate are slid down the length of the plate cylinder, and the ends of the plate are then locked using a lock-up device. The tube is then removed from the plate cylinder. Air bearings may be used on the mandrel or the plate cylinder, and the mandrel may be expandable.
