TLR-7 vs X300U for a G19?

Question

Adding a light to my G19 carry gun. Torn between the Streamlight TLR-7 (cheaper, smaller) and SureFire X300U (brighter, larger, more expensive). For AIWB carry and home defense, which one?

For AIWB carry specifically, **TLR-7** is the better call for most people. Reasons:

**Size matters in AIWB.** The X300U is noticeably larger and heavier than the TLR-7. In AIWB that extra weight and bulk rides right against your pelvis — you will notice it. The TLR-7 is dramatically smaller and you'll almost forget it's there.

**Light output is functionally equivalent for indoor use.** The X300U does 1,000 lumens; the TLR-7 does 500. Indoors, at 10-20 foot ranges, both are blinding. The X300U's extra output matters outdoors past 50 yards — irrelevant for carry use.

**Holster compatibility is better for TLR-7.** More holster makers support the TLR-7 across every carry position than support the X300U, particularly in AIWB-specific designs.

**The X300U's case for duty use:** If this were a duty pistol sitting in a retention holster all day, the X300U's durability and output would be the right call. The 2024+ X300U-B with the "T-slot" interface is genuinely tougher than the TLR-7 in hard-use scenarios.

**My concrete recommendation for your case (AIWB carry G19 with home-defense secondary):** TLR-7 Sub or TLR-7A. Save the $150, carry the smaller light, and you will not be outgunned in any reasonable home-defense scenario.
