Frequently Asked Questions

What is a Light LEM conversion for an HK USP?

A Light LEM (Light Action) conversion for an HK USP makes its trigger function similarly to a striker-fired pistol. It removes the spurred hammer, always keeps the hammer down in double-action mode, and provides a light, consistent pull to a defined single-action wall, followed by a single-action press and reset.

How can I add an optic to an HK USP?

To add an optic to an HK USP, you can use an optic cut system like the i-D.O. system by Right Armory. This system provides a plate system for future optic compatibility and ensures a low 1/3 co-witness, with a QPQ finish that resists corrosion and wear.

What are the benefits of the HK Jet Funnel magazine well?

The HK Jet Funnel is an accessory that increases the USP's magazine capacity from 15 to 18 rounds and significantly speeds up reloads by acting as a funnel. It also provides a point of leverage for the support hand during a two-handed grip.

Why is a weapon light difficult to activate on an HK USP?

The HK USP features a very large, oversized trigger guard designed for use with gloves. This design sets the weapon light further forward, making it difficult to reach conventional switches. An extended tail switch on the light is often necessary for easier activation.
