SD= Straight Drop, drop-off platform. The straight drop allows for better, faster draws. The platform can be made to accommodate holsters with Tek-lok attachment holes or holsters with the QLS system*, but platforms made for the QLS will not work for Tek-lok holsters and vice versa, they are separate items. Our SD platform for the QLS eliminates the cant of the Safariland holster that it has when using the Safariland platform.
Both versions of the platform have three levels for adjusting the height of the holster up or down.
A Tek-lok, all attachment hardware, and a leg strap with a buckle are also included with the platform.
