This diminutive unit is only 4.5" long overall; weight 12 oz. Colt did not manufacture this pistol, but rather had it made for them by Astra in Spain. Introduced in 1958. Chambered for .25 ACP. One year later .22 Short version appeared. Both had external hammers and detachable 6-round magazines. Passage of 1968 Gun Control Act, made import of a weapon this size illegal, so Colt discontinued its relationship with Astra. Pistol was re-introduced in 1970 as an American-made product and produced for two more years. Production ceased in 1972. Astra also made this pistol and called it the Cub. NOTE: Add 25 percent for .22 Short.
