Used this as the blackplate for safariland qls attached to els belt - Safariland 567BL Belt Loops for Model 567 567BL-1-2-175

To mount a pistol onto the Safariland ELS belt system, one can use either the ELS or QLS fork and receiver plate. Using the QLS kit is more stable than using the ELS kit. However, the QLS kit requires an additional back plate and this inexpensive item in review is the one that needs to be ordered.
Pros: stability
Cons: none
