Description
The TCM-10F is Nightstick's answer to the shrinking size of duty and carry setups without giving up any punch. It pushes out 650 lumens from a single CR123 battery, and thanks to an engineered TIR (total internal reflection) lens, that light gets shaped into a tight, bright hotspot that carries out to about 136 meters. You get a clean center beam for identifying what's in front of you and a well-defined outer halo so you still keep your peripheral awareness. The Flat Dark Earth finish keeps it low-key and pairs nicely with tan and coyote-colored builds.
What the TCM-10F Brings to Your Pistol
Controls are fully ambidextrous, with rear-facing toggle switches on both sides for momentary-on and constant-on operation. That means it works the same whether you're right or left handed, and it's easy to run without breaking your grip. There's also a user-programmable strobe mode and a battery-safe mode when you want them. Runtime lands at up to two hours on the high setting off one fresh CR123, which is solid for a light this size.
Fit and Build on the TCM-10F
The body is machined from aircraft-grade 6061-T6 aluminum with a polymer rear housing, and it's built to shrug off impact, water, and the usual abuse that comes with a carry gun. It measures roughly 2.5 inches long and tips the scale at only about 2.5 ounces, so it won't throw off the balance of a compact pistol. It ships with five handgun-specific modular rail inserts and comes pre-configured with the C1 insert for Glock pistols, covering well over 200 makes and models between them.
Getting the TCM-10F Mounted
Installation is quick with the included Allen wrench and hardware, and Nightstick even tosses in two spare screws. Because it shares the same footprint as the TCM-550XL, holster options are wide open. Whether it's riding a home-defense pistol or a duty gun, the TCM-10F is a lot of light in a package that stays out of the way.

Frequently Asked Questions
Will the TCM-10F fit my pistol?
The TCM-10F ships with five handgun-specific modular rail inserts that cover well over 200 makes and models with an accessory rail. It comes pre-configured with the C1 insert for Glock pistols right out of the box, so most Glock owners can mount up in minutes. For other platforms, just swap in the matching insert using the included hardware.
How bright is the TCM-10F and how far does it reach?
It puts out 650 lumens through a TIR lens, which shapes the beam into a tight, focused hotspot that reaches out to about 136 meters. You also get a defined outer halo that helps you keep your surroundings in view. That combination makes it well suited for quickly identifying what's downrange in low light.
What battery does the TCM-10F use and how long does it run?
The TCM-10F runs on a single CR123A lithium battery, and one comes included so you can use it right away. On the high setting you can expect up to two hours of runtime. To swap the battery, you unthread the bezel at the front of the light.
Does the TCM-10F work with existing holsters?
Yes. The TCM-10F shares the same physical footprint as the Nightstick TCM-550XL, so holsters built for that light will accommodate it. Its compact size also means it plays well with a wide range of light-bearing holster options on the market.
