Calico M110
Calico Light Weapons Systems · Pistol · Discontinued · 1989
Also known as: M-110, Calico 100+1
Overview
The Calico M110 is a blowback-operated semi-automatic .22 LR pistol manufactured by Calico Light Weapons Systems and built on the same helical-magazine architecture as the M100 carbine. The 6-inch barrel and aluminum receiver carry a 100-round top-mounted helical magazine, giving the compact pistol roughly five times the on-board ammunition of conventional rimfire handguns. Designed for plinking and small-game hunting, it has become a sought-after collectors' piece due to limited production runs.

Notes
Despite being marketed as a pistol, the long magazine cylinder gives the M110 a profile larger than most service handguns. The pistol uses a hammer-block and trigger safety; many users mount it in a registered-pistol-brace configuration for stability.
Background
Because the helical magazine sits parallel above the bore rather than feeding from the grip, the M110 is one of the very few production handguns where you can carry 100 rounds chambered without reloading - a feature so unusual it inspired the gun's appearance in cyberpunk video games and 'Demolition Man'-era science-fiction films.
