Bianchi's new SL3.2.1 SpeedLok Duty Holster was created as a response to officer concerns about weapon security. The SpeedLok's Auto Retention system secures automatically, preventing both weapon fallout and take away attempts without the need for snaps, bails, or other devices. The duty weapon can be twisted and pulled in any direction, but it cannot be removed from the holster unless you release the SpeedLok lever.
