Duration: 45:15

This video provides an in-depth comparison of popular handgun weapon lights, focusing on their momentary and constant-on control schemes. Instructor Roger Barrera, a former Las Vegas Metro PD officer, demonstrates various activation techniques and their impact on shooting performance during realistic low-light scenarios. He highlights the pros and cons of the Modlite PL-350's constant-on-only feature versus the momentary options on the SureFire X300 Ultra, Streamlight TLR-1 HL, and TLR-9, offering practical insights for tactical applications.

Quick Summary

The Modlite PL-350 exclusively uses a constant-on feature, unlike lights such as the SureFire X300 Ultra or Streamlight TLR-9 which offer both momentary and constant-on modes. This difference impacts how users activate and deactivate the light, with the PL-350 requiring manual shut-off and potentially alternative manipulation techniques to avoid altering grip.

Frequently Asked Questions

What is the main difference between the Modlite PL-350 and other handgun weapon lights like the SureFire X300 Ultra?

The primary difference lies in their control schemes. The Modlite PL-350 exclusively features a constant-on mode, requiring manual deactivation. In contrast, lights like the SureFire X300 Ultra, Streamlight TLR-1 HL, and TLR-9 offer both momentary activation (light on only when pressure is applied) and constant-on modes.

Can consistent pressure on a momentary weapon light switch affect shooting accuracy?

Yes, consistent downward pressure on momentary switches, such as those found on the Streamlight TLR-1 HL, can potentially affect shooting accuracy at distances beyond 15-20 yards. This pressure can cause shots to deviate low and left, especially for right-handed shooters under stress.

What are the advantages of the Streamlight TLR-9's control system?

The Streamlight TLR-9 is praised for its intuitive controls, allowing both momentary and constant-on activation with the same switch. It provides a positive click for tactile feedback, making it easy to switch between modes and use effectively during dynamic shooting scenarios.

How does the Modlite PL-350's constant-on-only feature impact its use in tactical situations?

The constant-on-only nature of the PL-350 means users must consciously deactivate the light manually. This is particularly important during actions like emergency reloads, where failing to turn off the light could reveal the shooter's position while the firearm is out of the fight.

What is the recommended holster compatibility for the Modlite PL-350?

Safariland ALS holsters designed for the SureFire X300 Ultra often fit the Modlite PL-350 without modification, as they retain based on the ejection port. However, Kydex holsters typically require specific designs made for the PL-350, as their retention is based on the light's dimensions.
