The Safariland QLS 22 Black Receiver Plate is the mounting platform for the QLS 19. This plate can be attached to any 3 hole backpiece - which could include a belt slide, or paddle, onto the front of an MLS 16, or onto basically any flat surface if you have the right screws. This plate retains a Level I retention on any duty holster. The MLS 16 would be weaved into Molle loops. This is a great all around tactical platform that can be appreciated by anyone from Police officers to competition shooters and amateurs.
