Few firearms are as instantly recognizable as the Calico M-950. With its distinctive top-mounted helical magazine, tubular receiver, and radically unconventional profile, the M-950 looks like something pulled straight from a Cold War era science fiction movie. Chambered in 9mm, the M-950 was designed around Calico's unusual helical feed system, giving the pistol a silhouette unlike virtually anything else on the commercial firearms market. Its combination of polymer and metal construction, rear mounted magazine assembly, and minimalist tubular design makes it a fascinating example of the experimental firearms engineering that emerged during the 1980s and 1990s. Today, the M-950 stands out as much for its collector appeal and mechanical uniqueness as for its distinctive appearance. For enthusiasts of unusual firearms, retro designs, and unconventional engineering, there simply isn't much else that looks or feels quite like a Calico. Futuristic styling. Unconventional engineering. One of the most distinctive 9mm pistols of its era.
