About-

Born from some of the best technology used in competition and refined for concealed carry, the Mako brings track-day performance to an everyday platform. Every line, cut, and port on the Mako serves a purpose — engineered for speed, control, and balance in real-world conditions.

At its core sits a custom G19–based frame, hand-finished for a secure, repeatable grip with undercuts, accelerator cuts, and an enhanced texture pattern for confident control under pressure. The hand fit inline 4 port barrel with a hand polished feed ramp reduces muzzle rise and keeps your sight picture flat, keeping your optic on target for faster follow-up shots — the kind of return you normally only see on the competition firearm.

Each Mako is equipped with a custom Poseidon x Apex Tactical trigger — tuned for a crisp, clean break and reset that shortens the wall without sacrificing safety. The custom slide rides smooth and true, topped with a co-witnessed oSight SE fully enclosed red dot and fiber optic backup iron sights, giving you redundancy and rapid acquisition whether you’re training, carrying, or defending.

Built with reliability at its heart and performance in its DNA, the Mako is where precision engineering meets practical purpose — a concealed carry pistol that hits like a full-size race gun.

The Spirit of the Mako-

Like its namesake, the Mako is built for speed and precision in the depths — streamlined, efficient, and unapologetically aggressive. Every Poseidon build carries that same spirit: forged in the deep, refined through pressure, and surfacing only when it’s time to strike. The Mako isn’t just a firearm — it’s the embodiment of control, confidence, and capability in motion.”

• What is the lead time? — If we are out of stock you can pre-order and the typical build and QC time is 4-8 weeks.
• Is the optic included? — Yes! Every Mako comes with the amazing oSight SE, a fully enclosed, 2MOA red dot installed and zeroed to a 15-yard laser bore sight
• Support and warranty? — Full Apex warranty applies to the co-branded trigger. Standard component warranties apply. Poseidon provides direct in-house service and coordination if needed.
