The Beretta Model 21A Bobcat is a small, double-action semi-automatic pocket pistol chambered in .22 Long Rifle or .25 ACP, designed for deep concealment, backup carry, and personal protection in contexts where absolute minimum size is the paramount requirement. Part of Beretta’s tradition of small pocket pistols stretching back to the early 20th century, the 21A represents a modern interpretation of the compact defensive pistol concept, offering reliable function in a package that can be carried comfortably in a pocket, ankle holster, or other minimalist carry configuration.
The 21A’s most distinctive and practically significant feature is its tip-up barrel design, which allows the barrel to hinge upward from the front, exposing the chamber for direct loading and unloading without requiring the slide to be cycled. This feature addresses a real limitation of many small semi-automatic pistols—the difficulty that shooters with limited hand strength or dexterity experience in racking a stiff slide—by providing an alternative method for the most common chamber management tasks. For elderly users, people with arthritis or injury-related grip limitations, or anyone who finds small-pistol slides difficult to operate, the tip-up barrel is a meaningful practical advantage.
The 21A is a double-action/single-action design with a spurless hammer, allowing double-action fire for the first shot from a loaded chamber without requiring manual hammer cocking. The safety is a conventional cross-bolt type that is simple to operate. Magazine capacity is seven rounds in .22 LR or eight rounds in .25 ACP—modest but adequate for the pistol’s intended application as a last-resort backup or close-quarters defensive tool.
Beretta has produced the 21A in standard and stainless configurations, and the design has remained in the catalog with minimal changes for decades, reflecting its success as a simple, reliable solution to the deep-concealment pistol requirement.
