The #31L is the current issue for Federal Flight Deck Officers. It is an asymmetrical pancake style holster with three slots for use as a strong side or cross draw. The 31L features a reinforced upper section and provision for padlock. The purpose of the padlock hole is to secure the weapon inside of the holster when it is not being worn. This also eliminates the need to load and unload the weapon when it is to be stored safely. Available in black. Belt slots are 1 3/4" wide.
