Langdon Tactical Technology has turned its attention to one of America’s most familiar defensive pump guns with the release of the new LTT Mossberg 590.
The company did not try to reinvent the shotgun. Instead, it started with the proven 12-gauge Mossberg 590 and addressed the areas that can make a factory pump gun feel a little rough around the edges.
LTT gunsmiths polish several internal components before applying an NP3 coating. That work is intended to smooth out the 590’s action right from the box. The coating contains embedded PTFE and should become slicker as the shotgun gets used.
The shotgun also receives an LTT trigger job. Langdon says the resulting trigger breaks at approximately 4.5 pounds, compared with the factory pull of roughly 6.5 to 7 pounds.
Other upgrades include Magpul furniture and LTT’s Labyrinth heat shield. The shield protects the shooter’s hand during extended firing and supports a thumb-over-bore grip. It also provides space for managing weapon-light wiring and switches.
An LTT Fastback optic mount places the red dot toward the rear of the receiver. That leaves more room for emergency port loading while keeping the optic window relatively clear. Buyers can choose mounts compatible with RMR, Aimpoint ACRO or Holosun 509T footprints.
LTT pairs that mount with its adjustable Super Duty Shotgun Sight. The rear sight offers windage adjustment, while the front provides elevation adjustment. Both can be adjusted without a dedicated tool or with the rim of a shotgun shell.

Langdon also lengthens and hones the forcing cone. The more gradual transition is designed to improve pattern consistency with buckshot and birdshot while slightly softening the felt recoil impulse.
The LTT Mossberg 590 uses a fixed cylinder bore and a 3-inch chamber. The standard version comes with an 18.5-inch barrel and Magpul stock. LTT also plans to offer a 14.375-inch Shockwave configuration.
The compact model can eventually serve as the foundation for a short-barreled shotgun, but owners must receive ATF Form 1 approval before installing a shoulder stock.
Langdon’s website does not currently list a separate MSRP. However, the company’s direct price for the available 18.5-inch model ranges from $1,534 to $1,623, depending on the selected configuration. The Shockwave version remains listed as “coming soon.”
