I want to share with those who are interested, my TLR1 Thumb Nut Modification.

I really like the TLR1, with the exception of the thin OEM thumb nut. Digging through my scope ring miscellaneous parts box, I ran across these thumb nut/cross bar combinations. The modification was very simple;

  • Disassemble the OEM thumb nut.

  • Open up the threaded hole in the OEM locking plate, to accept the replacement cross bar.

  • Press fit the replacement cross bar into the recess in the TLR1 locking plate.

  • Reassemble the modified thumb nut.

Now the TLR1 is easier to install and tighten by hand, and is easier to further tighten down with what ever may be available and inserted into the open “coin slot” of the new thumb nut (coin, knife blade, ect.). The OEM thumb nuts “coin slot” was simply too shallow, and easily stripped out. The thumb nut overall, was too thin with minimal serrations to adequately torque by hand.

that looks nice Quib but I’m confused on how you got the screw part attached to the light. did you press it in with a hydraulic press or did it go easier somehow?

Are you asking how I attached the new cross bar to the TLR1 locking plate?

yes

yes I am…

As you can see in the third picture, the head of the cross bar is not round, but sort of oval in shape.

After I drilled out the locking plate threads, large enough to slide the cross bar through, I pressed the locking bar head into the recessed hole in the locking plate.

To set the locking bar in place I used a punch and hammer. The fit was perfect.
