The Browning BDM pistol features a unique Dual Mode selector, allowing it to function as a traditional DA/SA semi-automatic ('P' mode) or a double-action-only system ('R' mode) mimicking revolver operation. This mode switching is accomplished via a tab on the magazine floor plate. An unusual safety feature automatically releases the slide and decocks the hammer when engaged with the slide locked back.

Quick Summary

The Browning BDM pistol offers two modes: 'P' (Pistol) for DA/SA semi-automatic operation and 'R' (Revolver) for DAO function. Mode switching is done via a magazine floor plate tab, and its safety lever uniquely releases the slide when engaged with the slide locked back.
