The Triton 9 is a clamshell-style 9mm PCC (Pistol-Caliber Carbine) designed to run Glock-pattern magazines. Built by DB Firearms, it draws heavily from the FGC-9 V2 while integrating a bufferless bolt system from Riptide Rails. The result is a clean, modular build with improved component compatibility and a sleek user experience.

Perfect for DIY builders who want something compact, reliable, and just a bit sci-fi looking.

One week until the Triton-9 files drop! I’ll be releasing them on 5/30 on my own odysee and with the Gatalog. I’ll be sharing details about this build over the next seven days so be on the lookout! pic.twitter.com/Iz12Sz1VfZ

Features of the Triton 9

The Triton 9 uses a clamshell design for its upper receiver, making barrel installation straightforward and rock solid. It supports Glock 9mm magazines and maintains FGC-9 compatibility with key upgrades.

It incorporates the Riptide Rails bufferless bolt system, allowing for a more compact and efficient design. You’ll also benefit from aluminum upgrades such as the mag catch, feed ramp, and charging handle — boosting both function and longevity.

AR-15 fire control compatibility means you can customize your trigger feel and controls with familiar hardware. The optional brace/stock system includes collapsing rods and locking mechanisms, making the build as portable or adjustable as you want.

And yes, there’s even a printed takedown latch that can be upgraded for more secure locking during firing. The Triton 9’s blend of performance and modularity makes it a go-to for builders who want something modern and practical.
