Weapon Light Guides
The weapon lights that fit and suit popular firearms — each pick research-verified for mount compatibility and graded for how well it suits the gun's job, balancing flood (lumens) against throw (candela).
Pistol lights
Rail lights for carry, duty, and home-defense pistols — graded flood-first for close-range work, with a candela ceiling indoors.
- Weapon lightsGlock 19Every weapon light that mounts on the Glock 19, ranked by how well it suits a do-everything carry and home-defense 9mm. The right pick has enough flood to identify a target across a room — not the hot, far-reaching candela that just bounces glare off close walls. Below: what fits, graded for the gun's job.
- Weapon lightsGlock 17Weapon lights for the Glock 17, the full-size duty and nightstand 9mm. A home-defense pistol rewards even, wide flood for fast target ID indoors over long-range throw. Here's every light that mounts on the Glock 17, graded for that job.
- Weapon lightsGlock 43XWeapon lights for the slim Glock 43X — the carry-priority 9mm where the light has to stay small enough not to print. Sub-compact lights rule here; below is what fits and which ones suit a concealed-carry gun.
- Weapon lightsSIG M17Weapon lights for the SIG P320-M17, the full-size service pistol. A duty light wants reliable, wide flood for low-light identification and a beam tuned for room-and-hallway distance. Here's every light that mounts on the M17, graded for the job.
- Weapon lightsS&W M&P9 M2.0Weapon lights for the S&W M&P9 M2.0 — a full-size duty and home-defense 9mm. Look for clean, wide flood to own a room without the wall glare a hot thrower bounces back at you. Here's what mounts and how each suits the gun.
- Weapon lightsHK VP9Weapon lights for the HK VP9. The full-size striker pistol takes a standard accessory rail, so the choice comes down to output and beam for duty and home defense. Here's every light that fits the VP9, graded for the job.
- Weapon lightsWalther PDPWeapon lights for the Walther PDP. A full-size duty 9mm wants wide, even flood for fast low-light ID over long-range throw. Here's every WML that mounts on the PDP's rail, graded for the gun's job.
- Weapon lightsFN 509Weapon lights for the FN 509, a duty-grade 9mm with a standard accessory rail. Pick by flood, runtime, and a beam sized for indoor distance. Here's what fits the 509, graded for the gun's job.
Rifle & carbine lights
Scout and rail lights for patrol carbines and PCCs — balanced flood-to-throw for close-to-medium range.
- Weapon lightsDDM4 V7Weapon lights for the Daniel Defense DDM4 V7. A 16″ 5.56 patrol carbine works close-to-medium range, so the ideal light balances wide flood with enough throw to reach across a yard or down a hall. Here's every light that mounts on the M-LOK rail, graded for that job.
- Weapon lightsBCM RECCE-16Weapon lights for the BCM RECCE-16. A do-everything 16″ carbine wants a scout light with balanced flood and reach. Here's every WML that mounts on the RECCE's M-LOK rail, graded for the gun's job.
- Weapon lightsS&W M&P15Weapon lights for the S&W M&P15 Sport. The everyman 5.56 carbine takes any rail-mount scout light, so the choice is output and beam. Here's what fits, ranked by how well it suits a home-defense and range carbine.
- Weapon lightsRuger AR-556Weapon lights for the Ruger AR-556 — a budget 16″ 5.56 carbine and a common home-defense rifle. Here's every scout light that mounts and how each is graded for close-to-medium work.
- Weapon lightsSIG M400 TreadWeapon lights for the SIG M400 Tread. A 16″ 5.56 carbine that lives at CQB-to-medium range — the ideal light balances flood and throw. Here's what mounts on the Tread, graded for the job.
- Weapon lightsCZ ScorpionWeapon lights for the CZ Scorpion EVO 3 carbine. A 9mm PCC is a close-range home-defense and truck gun, so it wants flood-forward output without the candela that bounces back indoors. Here's every light that fits, graded for the Scorpion's job.
