Top Handgun Lights Ranked by Data

1. SureFire X300U-A/B — The Gold Standard

The SureFire X300U is the king of handgun lights with 203 average upvotes — the highest community engagement of any weapon light. At 1,000 lumens with a focused beam, it's the light used by military, law enforcement, and serious shooters worldwide. The -A model uses a rail-clamp mount; the -B uses a thumbscrew mount. Most holster companies design around the X300 first.

Pros: Industry-standard holster compatibility, bombproof reliability, proven 1,000-lumen output.
Cons: Premium price, large profile for compact guns.

2. Streamlight TLR-7A — Best Compact

The Streamlight TLR-7A is the most frequently posted handgun light on r/gundeals with 49 tracked deals. Its compact form factor sits flush with a Glock 19 barrel, making it the go-to choice for compact carry guns. At 500 lumens, it's more than enough for indoor distances.

Pros: Flush-fit on compact guns, excellent holster support, ambidextrous switches.
Cons: 500 lumens vs 1,000 for full-size lights, limited throw distance.

3. SureFire X300 Turbo — Best Throw

The Turbo variant of the X300 uses a TIR lens for a tightly focused beam that reaches much farther than the standard X300U. At 650 lumens but with dramatically more candela, it's designed for outdoor use or situations where you need to reach out and identify threats at distance. At 87 average upvotes, deals generate strong community excitement.

Pros: Exceptional throw distance, same X300 form factor and holster fit.
Cons: Less spill/flood than standard X300U, premium pricing.

4. Streamlight TLR-1 HL — Best Budget Full-Size

The Streamlight TLR-1 HL delivers 1,000 lumens at under $80 — that's SureFire-level output at a third of the price. It's a full-size light that fits Glock 17 and similar duty-size pistols perfectly. Holster support is widespread.

Pros: 1,000 lumens under $80, great holster compatibility, proven reliability.
Cons: Slightly bulkier than X300, lower candela than SureFire.

5. Holosun P.ID — Budget King

The Holosun P.ID is turning heads at under $50. With respectable output, a rechargeable battery, and Holosun's growing reputation for quality optics, this is an incredibly compelling option for budget-conscious shooters. At 94 average upvotes from just 3 deals, the community is enthusiastic about this newcomer.

Pros: Unbeatable price, rechargeable battery, solid output.
Cons: Newer product with limited long-term data, holster compatibility still growing.

6. Modlite PL350 — Premium Compact

Modlite brought their rifle light expertise to the handgun world with the PL350. Using interchangeable heads and a rechargeable 18350 battery, it offers significantly more output than competing compact lights. The PLHv2 head in particular delivers exceptional candela for a pistol light.

Pros: Interchangeable heads, rechargeable, excellent output for its size.
Cons: Expensive, proprietary battery, limited holster options.
