Lancer LSX-3X Shotgun Extension Tube for Beretta 1301

Lancer LSX-3X Magazine Extension for Beretta 1301 Competition Plus

The Lancer LSX-3X is a purpose-built magazine extension designed to increase the ammunition capacity of your Beretta 1301 Competition Plus shotgun. This is a straightforward solution for shooters who demand higher round counts in competition or training scenarios.

Construction and Design

Materials: The extension combines machined aluminum components with a lightweight carbon-fiber tube. This hybrid construction delivers durability without unnecessary weight—a critical consideration for shotgun sports where you'll be shouldering the gun repeatedly throughout a match.

Capacity: The extension adds three additional rounds to your magazine tube, increasing your total on-board ammunition supply.

Features and Specifications

• Machined aluminum components for strength and reliability
• Lightweight carbon-fiber tube reduces overall gun weight
• Includes an extra-long spring that can be trimmed to your preferred loading specifications
• Direct attachment to existing magazine tube—no gunsmithing required
• Extension clamps are recommended for tubes that extend beyond the barrel

Practical Considerations

The included spring is intentionally oversized, allowing you to customize it to your exact loading preferences. This flexibility ensures reliable feeding with your specific ammunition and loading technique. For extended tubes, clamps provide additional support and prevent unwanted movement during shooting.

This is a no-nonsense upgrade for competitive shooters and serious practitioners who understand the value of increased ammunition capacity.
