It was chambered in .25 ACP, making it one of the smallest semi-automatic pistols of its era. The design features a striker-fired mechanism with a fixed barrel and blowback operation. It was widely carried as a discreet civilian self-defense weapon. The pistol was also sold by Colt in the United States as the Colt Model 1908 Vest Pocket.

The Beretta 21A Bobcat is a compact, tip-up barrel pistol designed for deep concealment. Chambered in .22 Long Rifle and .25 ACP, it features a unique barrel pivot that allows loading the chamber without racking the slide. The Bobcat is one of the smallest production autoloading pistols ever made. Its tip-up design makes it especially suitable for users with limited hand strength. The pistol has remained in continuous production since its introduction in 1984.

The FN Baby Browning is a compact blowback-operated semi-automatic pistol chambered in .25 ACP. Designed by John Browning, it is a smaller version of the earlier FN Model 1905 Vest Pocket pistol.

The Baby Browning features a simple blowback action with no safety catch, relying on a half-cock notch for carrying safety. It was manufactured continuously by Fabrique Nationale from the 1930s through the 1970s.

The Beretta 950 Jetfire is a diminutive tip-up barrel pistol introduced in the 1950s. It is chambered in .25 ACP and features a very small frame optimized for pocket carry.

The pistol was produced for decades and inspired Beretta's later Bobcat series.

The Colt Model 1908 Vest Pocket is a compact blowback semi-automatic pistol designed by John Moses Browning. It was chambered in .25 ACP and designed for discreet personal defense.

The Model 1908 was the smallest Colt automatic pistol of its time. It remained in production for over three decades and sold widely in the American civilian market.
