The pistol grip was slung under the rear portion of the stamped-steel receiver in the usual way with a large trigger loop designed for a gloved hand. An optional forward vertical grip could be added under the forend for the support hand. The forend covered the entire section of barrel usually partially exposed on other submachine gun designs. The forend featured four large slots to each side for proper heat dissipation with the internal bolt assembly used as part of a 'forced-draft' system, pumping in cooler air into and around the barrel.
