The Streamlight TLR-4 is a dedicated weapon light and laser combo built specifically for HK USP Compact pistols. If you carry, train, or compete with a Compact and want a single module that puts a bright targeting beam and red laser on target, this is a purpose-built solution that mounts directly to your slide—no adapters or guesswork. The 170-lumen C4 LED throws enough light to identify threats and targets at typical defensive distances, while the integrated red laser gives you a second aiming reference that's especially useful in low light or from unconventional shooting positions.

Streamlight engineered the TLR-4 to be compact and lightweight; it doesn't bulk up your carry or range gun. The black anodized polymer housing is durable and corrosion-resistant, standing up to holster wear and outdoor use. Activation is intuitive—momentary or constant-on modes let you control when the light and laser are active, which matters both for tactical discipline and battery life.

This is the kind of accessory that pays dividends in training. The dual light-and-laser setup lets you verify your point of aim in dim conditions, cross-check your sight picture, and work through scenarios where your primary sights might be obscured. Whether you're running low-light drills at the range, defensive training, or just want a serious backup aiming system on your Compact, the TLR-4 delivers proven Streamlight reliability in a form factor that actually fits your gun.
