Beavertail for MX-1 Glock 17/19/45 Gen 6

Take Your MX-1 Chassis System to the Next Generation

Your MX-1 chassis already delivers broad compatibility across Glock Generations 3 through 5. Now you can bring Glock’s latest platforms into the same system with the MX-1 Gen 6 Beavertail Expansion.

Engineered specifically for the new Gen 6 Glock 19, Glock 17, and Glock 45, this adapter gives you a precise, factory-level fit inside your existing MX-1 Glock Chassis System. The updated frame geometry locks in securely with zero play and zero wobble — even during rapid fire or hard use.
Turn your Gen 6 Glock into a stable, carbine-style platform in seconds.

Key Features
