[Review] Meta Tactical MX-1: Best Glock Chassis?

It seems like a rite of passage that gun owners have to own a Glock or similar firearm and fit some form of chassis system on it. Then they start running into the typical chassis problems, and the kit ends up at the bottom of a closet.

The Meta Tactical MX-1 has been designed by a team with experience in those chassis systems. They thoroughly researched the downsides and worked to address them. We took those claims to the range to determine how the MX-1 can elevate your Glock to the next level.

We put two MX-1 kits through the ringer to show you exactly why the Meta Tactical MX-1 is different and what it can do for you. This includes multiple guns, varying configurations, and hundreds of rounds of 9mm ammunition, along with an appetizer’s worth of 10mm ammunition.

The Glock Chassis Market

This isn’t Meta Tactical’s first foray into the world of Glock conversion kits. They made this awesome bullpup rifle conversion, which I absolutely adore. Their venture into a Glock chassis kit is likely a move that’s more appealing to most shooters, but I encourage shooters to try the Apex kit; it’s fantastic.

The MX-1 made its debut at SHOT 2025. What drew me to it was the modularity. They were promising one kit that fit every Glock, or basically every Glock.

No other kit has done that. This piqued my interest, but as someone who has done a lot of experimentation with these chassis, I was still wondering if they would fall victim to the faults of other chassis.

Luckily, I’m in a position to find out!

The Meta Tactical MX-1 comes with a wide variety of folding stocks or folding braces. You get to pick between metal or polymer, and polymer tends to be the more affordable option. Users can pick between a short brace or a short stock. I opted for the short brace so it would fit my forearm a little easier.

The MX-1 is a bit like a chicken dinner here in the south; it has to come with all the fixings.

I saw the MX-1 at SHOT and noticed it had a polymer optics rail, but it seems like they made the wise decision to swap that to metal, and it’s long enough to put an optic anywhere. Additionally, the front half of the kit is covered in M-LOK slots for all your accessory mounting needs.

I’ve practiced the fine art of burying the lede. Let’s talk modularity.

The MX-1 allows you to swap out different parts and pieces so the kit can accommodate Glocks, both big and small, and Glock clones from PSA, P80, and Ruger.

The P80 frame is universally popular with Glock clones, so it will likely fit a ton of different clones. The first step is to use the correct beavertail adapter. This installs with the twist of an Allen key.

The keys have different initials that correspond to the correct Glock frame. Some are simple; they are just marked P80. Others use an initial, and Meta Tactical has a key on their website to help you figure out the right one for your gun.

The magazine holder utilizes a set of shim kits to accommodate magazines of various sizes. The holder without a shim fits your big 10mm and .45 ACP magazines. The other shims shrink the gap, so it works with 9mm magazines, single-stack magazines, and all the in-between options.

Shooting the Meta MX-1: Accuracy & Reliability

I had two kits, and the Glocks of choice I used were a Polymer80 compact 9mm and a Glock 20 10mm. Two kits, two very different guns, and two calibers would give me a good idea of how the MX-1 handled.

The first thing I wanted to test was accuracy – specifically, how the MX-1 can enhance accuracy and potential range. Additionally, the big problem with these chassis systems is a wandering zero. With many of these kits, you encounter a problem when removing the Glock from the chassis and reinstalling it.

The zero shifts because the gun isn’t indexing in the same spot every time. That’s the biggest problem with these chassis systems. Is that a problem with the MX-1?

I buried the lede before, but I’ll give it to you off the bat. No, this isn’t a problem. After zeroing the dot onto the gun, I fired a 5-round group at 20 yards inside of a 2-inch circle.

I removed the gun, reinserted it, and fired another group in another circle. Then I repeated it, over and over. I did the drill six times, and I could not see any zero shift.

I stepped back to 50 yards, shot at a 10-inch gong. I can hit this gong at 50 yards all day with the MX-1, but I wanted to check for zero shift again, at a much longer range. So I shot the gong, removed the gun, drank some water, reinserted the gun, and shot again.

No shift, I nailed the gong with every shot. I repeated this over and over, and there was no noticeable shift. It resolves my major issue with chassis systems.

How does accuracy stand up as a whole? Pretty dang well! Those 20-yard groups into 2-inch circles were all basically one ragged hole.

Both the 9mm and the 10mm were exceptionally accurate from the MX-1 kits. The brace allows you to better stabilize the gun, resulting in significantly improved groups overall. From 50 yards, I can hit gongs as small as 6 inches with ease and can nail 33% reduced-size IPSC targets.

At 100 yards, I can hit a full-sized IPSC target. I can do it with both the 9mm and 10mm, but it’s a bit easier with the 10mm to consistently hit where I want. The 9mm seems to be moving around quite a bit at 100 yards.

Reliability wasn’t a big deal either. The massive ejection port allows the shells to clear the gun without a problem. It ejects easily and cycles easily, but my only problem seems to be tied to one 9mm magazine. However, that magazine appears to be wearing out and causing trouble on multiple platforms.

Ergonomics: Fit & Feel

The ergonomics are mostly good. My only problem is easily resolved by better hand placement. At the top of the gun, you have M-LOK slots that are open, and the muzzle of the Glock is right below that.

If your thumb drifts up onto those slots, you are going to catch a little muzzle blast to your thumb. With the 9mm, it’s not a big problem. You can feel the blast, and you might get a little black on your finger, but it’s not a big deal. The 10mm offered a bit more blast, and uh, it can hurt.

It’s certainly uncomfortable, so watch your thumbs.

Besides that, we have some solid controls. We have an AR-style charging handle that makes it easy to manipulate the slide. The slide release is fully accessible, making reloads easy and fast. The magazine release is easy to access, and again, it helps ensure your reloads are fast.

The chassis doesn’t get in the way and doesn’t prevent you from getting a nice high grip on your Glock of choice. The MX-1 does a great job of not interrupting the natural controls and ergonomics of your pistol platform.

Who Is the MX-1 For?

The MX-1 is perfect if you’ve ever looked at a Glock chassis and thought, “Hey, I need that.”

Compared to other chassis systems, it’s not going to give you the same reliability and accuracy issues.

It’s great if you own multiple Glocks and want to transform one into a subgun-like platform. It’s also a great option if you live in a state where owning something like a CZ Scorpion, an MP5, or other similar firearm is exceedingly difficult.

You can transform your Glock into a platform that mimics the capabilities of those weapons fairly well. Handguns often have their own restrictions, but are much less likely to be classified as assault weapons.

The MX-1 is a lot of fun, and if you’re like me and you embrace the fun side of firearms, it’s a great accessory.

By the Numbers

Reliability: 5/5

There were no reliability issues with the 9mm P80 of the 10mm Glock 20. There were never any failures caused by the MX-1

Ergonomics: 4/5

The MX-1 allows you to easily access your gun’s natural controls and provides an awesome charging handle. Watch your thumb placement, though!

Accuracy: 4/5

The MX-1 will increase your gun’s effective range and accuracy, but it can’t turn a pistol-caliber weapon into a precision platform.

Customization: 5/5

Using a Glock as a host firearm significantly increases customization, and the MX-1 offers various rear-end stock and brace options, a long optics rail, and numerous M-LOK slots to top it all off.

Value: 3/5

At $300, this isn’t a cheap accessory, and the price only increases as you add more accessories.

Overall: 4/5

The MX-1 addresses the issue that Glock chassis kits have long faced. It allows for increased control, accuracy, and range while maintaining zero and having no reliability issues.

Upgrades & Accessories for the MX-1

The new Holosun ARO provides an affordable and reliable red dot that’s making itself the new king of the budget red dot.

The Streamlight TL RM 2 features a unique design that complements the compact nature of the MX-1.

If you’re going big with a chassis kit, then you might as well go big with your magazines! Glock OEM 33-round magazines are still the most reliable extended Glock magazines on the market.

How We Tested the Meta Tactical MX-1

I fired 300 rounds of 9mm through the P80 and MX-1 and 100 rounds of 10mm through my second MX-1. The price of 10mm makes it a bit pricey to test to great degrees, but I was pleased with the performance of both guns.

I also ran a reload after reload with the MX-1 to test the ergonomics and function of the gun in the chassis system. Accuracy testing was done off-hand to better simulate real-world use of the platform.

Final Verdict

The Meta Tactical MX-1 was a pleasant surprise. I didn’t expect it to fix all the problems I’ve previously had with the entire genre of Glock chassis kits. Yet, here we are. I’ve shot Roni kits, Kidon kits, and more, and never had this level of performance.

This is the only Glock chassis I’d ever use for defensive applications. I trust it that much. What do you think? Let us know below! For more conversion kits, check out our article on the Best Glock Conversion Kits.
