The Jimenez JA-22 is a .22 LR caliber pistol with a slide and frame made of Zamak, a zinc alloy.

Bryco Arms, Jennings' parent company, declared bankruptcy in 2003, and was subsequently purchased by the company's former foreman Paul Jimenez.

The pistol is blowback operated and striker fired.

[4] A 2001 Bureau of Alcohol, Tobacco, Firearms and Explosives publication warned that the pistol is "extremely dangerous" when dropped, with the "potential for serious injury", due to an insufficient gap between the trigger bar and the sear.

[5] The factory manual advised carrying the gun with the chamber empty.
