Description
The Meta Tactical MX-1 takes a familiar handgun and wraps it in a compact, stabilized chassis that handles more like a PDW. This is the MX1-PS-BK version, built around a CNC-machined 6061-T6 aluminum frame with a matte black hard-anodized finish and finished off with a black polymer side-folding stabilizer brace. Your pistol drops in through a patented tool-free locking system, so there's no gunsmithing, no permanent changes, and you can pull your Glock right back out whenever you want it as a standard sidearm again.
What the MX-1 Chassis Brings to the Table
The standout feature here is reach. Instead of a model-specific shell, the MX-1 uses swappable beavertail adapters that bolt into the rear, and the kit ships with the full set so one chassis can move between a Glock 19, a Glock 20, a PSA Dagger, and more just by changing a part. It covers 70+ Glock models across Gen 3, 4, and 5, along with Polymer80 PFC9/PFS9/PF940C/PF940V2 frames, the PSA Dagger family, and the Ruger RXM. Gen 6 Glock 17/19/45 owners can get in on it too with the separate expansion beavertail.
Controls and Mounting Room on the MX-1
Up top sits an AR-style charging handle that grabs the nose of the slide, so racking feels natural if you're coming from a rifle background, and your Glock's magazine release and slide catch stay within easy reach. The full-length Picatinny top rail gives you a clean spot for a red dot or magnified optic, while M-LOK slots along the sides and a bottom Picatinny section open the door for lights, grips, and a sling. The polymer folding brace swings to the side and locks rigidly when deployed, dropping the overall footprint down to around 14 inches folded from roughly 23 inches extended. The whole rig runs light, in the neighborhood of 1.6 pounds before you add a pistol and accessories, which makes it an easy one to stash in a bag, a trunk, or a home safe.
Worth knowing before you build it out: the charging handle pulls on the front of the slide, so this setup runs with a bare muzzle rather than a muzzle device or suppressor, and it's designed around standard-height sights rather than slide-mounted red dots or suppressor-height irons.

Frequently Asked Questions
Which pistols does the MX-1 conversion kit fit?
The MX-1 is built to cover 70+ Glock models across Gen 3, 4, and 5, plus Polymer80 PFC9, PFS9, PF940C, and PF940V2 frames, the PSA Dagger family, and the Ruger RXM. It uses swappable beavertail adapters to adjust for different frame shapes, and the full set ships in the box. Gen 6 Glock 17, 19, and 45 pistols require Meta Tactical's separate Gen 6 expansion beavertail.
Do I need tools to install my Glock in the MX-1?
No gunsmithing is required. The MX-1 uses a patented tool-free locking system that lets you drop your pistol in and lock it down, then pull it back out whenever you want your Glock as a standard sidearm again. You may need a hex or T10 wrench once to set the correct beavertail for your frame, but the pistol itself goes in and out without tools.
Can I run a suppressor or muzzle device with the MX-1?
This setup is designed to run with a bare muzzle. The AR-style charging handle grabs the front of the slide to cycle it, so there isn't clearance for a suppressor or muzzle device out front. It's also built around standard-height sights rather than suppressor-height irons or slide-mounted red dots.
What optics can I mount on the MX-1?
The MX-1 has a full-length Picatinny top rail, so you can mount a red dot or a magnified optic right along the top of the chassis. Reviewers have run everything from micro red dots to larger enclosed optics on it with good results. The chassis itself doesn't use a slide-mounted red dot, so the top rail is your mounting point.
