FN Model 1906

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. Its diminutive size made it popular for concealed carry and as a backup weapon. 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 Jetfire uses an inertia firing pin rather than a hammer or striker. Its tip-up barrel eliminates the need to rack the slide. 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 pistol has a distinctive grip spur at the rear of the frame instead of a true mainspring housing. It features a seven-round detachable box magazine and a simple tip-up barrel for easy cleaning. 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.
