- The Geissele Defense Pistol MOD1 (GDP MOD1) Highwayman was developed to add fully ambidextrous capability to the Highwayman platform originally designed for state police requirements. The GDP MOD1 Highwayman retains the performance characteristics of the Highwayman platform but enhances adaptability and ergonomics in the form of a fully ambidextrous lower receiver also used in Geissele’s Super Duty® MOD1-A and GFR® MOD1 rifles.
- A magazine release on the left side of the receiver below the Maritime Bolt Catch makes mag changes swift for left-handed use. The right side of the receiver features bolt catch and release buttons below the ejection port. The shooter uses the dust cover to apply pressure to the bolt catch to lock the bolt open, and a release button just rearward easily sends the bolt forward. This instinctive system doesn’t just accommodate left- or right-handed use; it enhances mechanical flow under pressure. Reloads and malfunction clearances are faster and more consistent—critical when seconds matter. Whether on the move or on the bench, everything works in concert to meet real-world performance demands. The dual-telescoping GDP MOD1 brace intuitively opens by simply pulling to the rear and can be deployed from its stowed position immediately and effortlessly. The brace has two solid-lock positions for deployment and requires the deliberate, but simple use of the trigger and detent mechanisms to collapse. The GDP brace utilizes a sturdy Velcro strap for one-handed support that attaches with two ITW C.L.A.S.H. Hooks (Conventional Latch Attachment Snap Hook). The GDP brace design allows unimpeded access to all firing controls even when fully collapsed. Reliability and shooting performance are at the forefront of the GDP MOD1 Highwayman design. Utilizing the patented Geissele Phased Array® gas system, the GDP MOD1 Highwayman is precisely balanced to optimize the 10.3” barrel length. The Geissele Tri-Port® System works in concert with the monolithic bolt carrier buffer system and custom length Super 42® braided buffer spring to achieve surprisingly smooth and controllable recoil impulse. The barrel is Cold Hammer Forged and chrome-lined with a tapered profile, sporting the HUXWRX Flash Hider-QD 5.56 for easy mounting of the patented HUXWRX Flow series of suppressors. The Forged Stressproof Bolt® is made from Carpenter 158+, directly developed with Carpenter Steel metallurgists to create a material that is cleaner and has less impurities. This makes the Stressproof Bolt® stronger and more fatigue resistant, capable of 5 times the life of a mil-spec bolt. The GDP MOD1 Highwayman features the proven controls and components of the Super Duty line, including the SSA X® trigger, MK16 rail, Airborne Charging Handle, Super Configurable Safety, Maritime Bolt Catch, Anti-Strike Super Compact Gas Block and ergonomic A17 grip. Compact and adaptable, the GDP MOD1 Highwayman is built to meet the demands of those who spend their days covering the long road, where readiness and reliability matter most.
