The Streamlight TLR Low Profile Lighting System pressure switch will probably not work on a Pump action shotgun. Depending on what model shotgun you have the light listed at the link below may work.

Streamlight only lists the CR123A batteries as compatible.
This does not, it is just a constant on or off.
The Streamlight TLR Low Profile Lighting System should work with the SureFire Weapon Light Switch as well as the Modlite Switch.
The Streamlight TLR RM2 is 4.55" long and the switch is around the same length. MLOK to picatinny adapters at the link below will work for mounting the Streamlight TLR Low Profile Lighting System to an MLOK handguard.

The Streamlight TLR Low Profile Lighting System could mount to 7 Picatinny Rail Slots. The light itself is 4.55" long and the switch is around 3" in length.
I recommend contacting Streamlight in regard to where the Streamlight TLR Low Profile Lighting System is made.
Yes it does. It features Streamlight’s “Ten-Tap” system where you can program it either constant or strobe. You can switch between the two by pressing the button 9 times and holding it on the 10th until it blinks.
A standard 4-6 slot rail section will work.
It is about 6 inches.
