The QLS 19 Locking Fork mounts directly to the back of any Safariland 2-hole pattern pouch or 3-hole pattern holster. The combination can then be connected to either the QLS 22 or QLS 22L Receiver Plate. Use with either of these receiver plates allows for quick transfer of holster between attachment points such as a belt loop, tactical leg shroud or other stable mounting platform. The QLS fork and plate combination passes the Level I Retention pull test.
