Langdon Tactical Technology already has shotgun work in its lineup, but the LTT Mossberg 590 marks the company's first move into pump-action shotguns specifically. Rather than changing what the 590 is, LTT is positioning this as a refinement of a platform that was already proven, focusing on the parts of the gun that shape how it actually runs and shoots. The core of the package is an action job with NP3-coated internals on the components that interact during cycling, which LTT says is aimed at smoothing out the stereotypically rough Mossberg action. Trigger work follows the same approach: an LTT trigger job paired with a new spring and NP3 coating brings the break weight down to roughly 4.5 pounds, compared to the factory 590's 6.5 to 7 pounds. Sighting gets a full overhaul as well. LTT pairs its Fastback optic mount with a new Adjustable Super Duty Shotgun Sight, and the two are meant to work together as a set, with the optic sitting behind a low-profile rear iron sight to keep the port area clear for emergency reloads. The rear sight adjusts for windage in 1 MOA clicks and the front post adjusts for elevation in 0.5 MOA clicks, both without tools, and the Fastback mount is available for RMR, ACRO, and 509T footprint optics. LTT also lengthens and hones the forcing cone, a treatment that the company says improves shot patterning and reduces perceived recoil. Furniture is Magpul throughout, paired with LTT's Labyrinth Heat Shield, which the company says manages weapon-light wiring and supports a thumb-over-bore grip technique while shielding the shooter's hand from barrel heat. Mitchell Booth, LTT's Product Development Manager, said the company's intent with the 590 was to refine the areas of a proven pump gun that make the biggest difference to the shooter, rather than reinvent the platform outright. The LTT Mossberg 590 ships in two configurations, an 18.5-inch Standard model and a 14.375-inch Shockwave model (images directly above and below), both built on a 12-gauge, 3-inch chamber with a fixed cylinder bore choke. Pricing on Langdon Tactical's site runs from $1,534 to $1,623 depending on configuration and optic footprint selected. Both versions are listed as available now through Langdon Tactical directly, and as serialized firearms, they move through the standard FFL transfer process. Would the Shockwave configuration appeal to you here, or does a build like this make more sense on the full-size Standard model?
