FAQ For:Apex Carbine Conversion Kit for Glock 20 (Gen 3-4 & SF)

Do you offer Dealer/Wholesale pricing?

Currently, we will offer kits that are compatible with Glock, S&W, and P80. This includes most make, models, and generations. Calibers to include 9mm, 10mm, .40, and .45. Future kits will be available for SIG Sauer and Springfield. If you don’t see your gun when ordering, please reach out to us on our contact us page and we can either confirm compatibility, anticipated manufacture timeline or provide more information.

Most handguns will require a specific chassis and 16” barrel engineered for that model, make, etc.

The kit includes the chassis and 16” drop-in replacement barrel.

The MX1 is equipped with integrated M-LOK slots positioned around the entire chassis allowing you to customize your setup with accessories such as optics, foregrips, lights, and more.

Yes, there is a thumb safety.

The overall length with a fully extended stock is 26” and 23.375” in the collapsed position. The weight is right around 3.25 lbs depending on the model and barrel combination.

Precision machined 16” Chromoly full drop-in barrel replacement with a black nitride finish. Polygonal rifling.

The threading on the 16” drop-in barrel is a proprietary thread and won’t accept aftermarket products including a suppressor. The added weight of a suppressor or potentially a different compensator will negatively affect the accuracy of the platform.

Yes, the kit is compatible with custom slide cuts and aftermarket slides.

Yes, as long as your magazine has the LRBHO feature on the follower.

Yes, the ejection port is ambidextrous due to our shell deflector.

Our CCK trigger linkage mechanism will retain the trigger pull and break weights of the trigger you have installed as well as retain your trigger’s reset. The trigger pull distance may be increased by a few hundredths of an inch (especially on flat-faced triggers), however, your reset will remain the same. The only difference is that our trigger linkage mechanism is providing a flat trigger pull as it is guided straight back, removing any ”curve” you may be used to in other firearm triggers.

Yes, we will offer our brave women and men of the military, LE, and First Responders a discount. Please fill out our first responders form to qualify.

400 rounds through it so far and all is well! Only issue is that the finish on the flash hider smudged away like spray paint when I used the included wrench on it. All else is superb. Makes the 10mm so much fun to shoot. Accuracy is impressive too.

    I like the package as a great concept, however I have a problem with mine in 10mm. My Glock 20 works fine in the shell using .40 s&w. But the 10 mm ammo causes the mag to drop with every shot. It only happens when inside the conversion kit. I feel the extra power of the 10 mm rounds causes the pistol to rotate slightly in the conversion unit and may cause the mag release to rub against the inside of the kit. I’m a tinkering kind of a guy so I’m going to void my warranty and try to solve this mag drop issue. Any pointers will be well received. I really like the system. It’s fun with .40 cal. Even cheaper to shoot than 10 mm, but I really want to perfect it for 10 mm.

    So much fun to shoot! Really smooths out the 10mm. Once I zeroed the optic, much better accuracy at range than the factory barrell! Good job you guys!

  3. A

    Excellent fit, finish, design and customer service.

    Overall happy with product though did buy a single stack mag holder to fit in-between the stock and compartment since I don’t have it fully collapsed. Have this as an attachable feature like the foregrip option might be popular. Would also have liked an option to have a bigger pistol grip to do the same as the foregrip and have a magazine in there as well. With it being light weight carrying extra mags on the rig would not be a be a huge increase in weight overall.

  5. JA

    Apex system is amazing! Recoil is non existent and the accuracy out to about 50m was on point. This is now my go to home defense weapon.
