Description
The Nightstick TWM-350 is a full-size, rail-mounted pistol light built around a CREE LED putting out 350 lumens and 12,000 candela. Paired with a deep parabolic reflector, that gets you a usable beam rated to 215 meters with a tight center hotspot and enough spill to light up a room. It's a genuinely versatile setup, tight enough to reach across a yard and floody enough to work inside a hallway.
What Sets the TWM-350 Apart
The standout here is the switching. You get ambidextrous toggle switches on both sides, so lefties and righties operate it the same way. Flip up for constant-on, press down for momentary. It's a simple, tactile setup that lets you manage your light discipline without shifting your grip. Runtime lands around 2.5 hours on a pair of CR123 lithium batteries, which come in the box, and the LED itself is rated for 50,000-plus hours.
Built to Take a Beating
The housing is aircraft-grade 6061-T6 aluminum with a Type III hard anodized finish, so it shrugs off corrosion and holds up to recoil, which Nightstick recoil-tests these for. It carries an IP-X7 waterproof rating (submersible to a meter for 30 minutes) and a 2-meter drop rating, plus it's chemical resistant. The whole thing weighs 5.4 ounces with batteries and measures 3.75 inches long, so it won't throw off the balance of a full-size pistol. There's even a serial number on each unit for personal identification.
Fitting It to Your Pistol
Mounting is handled through a modular cross-rail insert system. The kit includes inserts for GLOCK, Picatinny/1913, TSW/99, and 90two rails, so it'll drop onto a wide range of full-size handguns. Swap in the insert that matches your frame, snug it down with the included Allen wrench, and you're set. Folks running it on duty guns like the Gen 5 Glock 17 report a bright, white beam with a solid throw and a clean hotspot that holds up to daily carry.
