Last week, we talked a bit about obsolete firearms controls over at the ForgottenWeapons.com blog, and that discussion made me think of a fairly recent pistols with a fairly unique feature, the Browning BDM. Mechanically, the BDM is a pretty standard modern automatic pistol - it uses the ubiquitous Browning short-recoil system, and feel like most other service handguns. What makes it unique is the trigger and hammer setup, which are designed to replicate the manual of arms for either a DA/SA automatic or a double action revolver. I think the idea was to minimize the amount of retraining necessary for a police department that decided to switch to issuing BDMs.
