One of less than 250 manufactured between 1955 and 1958. The Kimball was a failed attempt at producing a blowback pistol in 30 Carbine using a series of cut rings in the chamber. In theory, on ignition the casing would swell to fill these rings, delaying extraction long enough for pressure to drop. Of only about 238 manufactured, many were destroyed during use by the severe recoil, making examples in this kind of condition even rarer. Blade front and adjustable rear sights, with the Detroit address on the left side of the chamber, serial number on the right, and finely checkered plastic grips.

Excellent. 95% original blue finish remains with small scratches and nicks, areas of mild edge wear, and handling marks overall. Grips are very fine with numerous small dings. Mechanically excellent. Includes two magazines (one magazine is missing the follower).
