Tactical Development TD-SF1 A Surfire X300 Key For P356 XL
 
This only works for the Surefire x300 lights with the ' T-slot thumbscrew clamp ' (see listed lights below) and our P365 XL Tactical Application Rail and ProLedge XLTAR.
 
If you are familiar with these inserts they act as a 'stop' and a 'indent'
 
Install: Same way you install the inserts that come with this light.
 
Tested Lights: (basically any with T-slot thumbscrew clamp)
SureFire x300U-B 
 
Not Tested: (same design as above)

SureFire x400UH

NOTE - Your only buying the small insert not the light or the gun or anything else.
