Manufactured circa 1958-1962, the Dardick 1500 uses a novel combination of a fixed in-grip magazine, an open-sided auto-ejecting three chamber cylinder and a proprietary plastic-cased triangular cartridge dubbed the "tround". This combination permits an ammunition capacity comparable to an automatic pistol while retaining the simple reliability of a revolver. Additionally, the barrel is secured with a single threaded bolt and can be rapidly detached or swapped. This pistol is currently equipped with a Dardick Corp marked .30 caliber barrel and fit into a carbine conversion unit. The serial number PT1 can be seen inside the grip behind the follower. Includes a box of 19 .38 special Trounds. Provenance: The Supica Collection
