Best Glock Conversion Kits

So, you want a newish firearm but don’t have the money to drop on a brand-new gun? Oh, and you happen to have a Glock laying around?

May I present an option...the conversion kit.

What is a conversion kit?

It gives you the means to expand the capabilities of your already trusty Glock into a personal defense weapon with extended range, improved accuracy, and more!

We’ve thoroughly analyzed the marketplace for these conversion kits to determine the best of the best.

So, follow along as we break down which Glock conversion kits you should consider.

Best Glock Conversion Kits

Before we dive in, it’s worth mentioning that you have to be really careful with conversion kits.

Many of these can turn your handgun into a Short-Barreled Rifle or Any Other Weapon. This means you need to register the thing if you want to avoid giving the ATF a reason to kick down your doors.

As always, do your research on any conversion kit on the market and the applicable laws before purchasing/putting your handgun in it.

Looking for something super lightweight but still gets the job done?

You can't go wrong with the Recover Tactical 20/20 conversion kit that we tested head to head vs the Roni.

See it in action here using a PSA Dagger which also fits (and makes it super affordable).

The 20/20 requires the use of an Allen key but besides that you're good to go.

Plus it has just enough rails for the average user (you can add them to both sides if needed).

It's also easy to put on a suppressor compared to the Roni since the barrel is exposed.

Want to use a red dot?

Our latest build has one with a riser...get their upper rail add-on or get a high mount like I have.

And for even more points of contact and ability to add an extra mag...see their angled mag pouch.

If you’re looking for a conversion kit that’s easy to assemble with no tools – grab a drop-in style kit such as the CAA Micro Conversion Kit.

This kit allows you to insert your Glock in a matter of seconds, making for a very quick and seamless transition.

Once you have your Glock converted, you’ve now drastically improved accuracy out to 200 yards.

Want to add a red dot, flashlight, or other accessories? Thanks to both its side and top Picatinny rails, there’s plenty of space to do that here.

The CAA MCK is ambidextrous, meaning that you can easily use it regardless of whether you’re a righty or lefty.  

For ease of one-handed use, this kit comes with an arm brace stabilizer and a Velcro strap. It also easily folds out of the way when not in use.

And, with the addition of a front spare magazine holder, you’ll always have ready access to another mag for seamless reloading.

The CAA MCK gives you a lot of leeway when it comes to universality as well.

Whether you have a Glock 17, 19, 19X, 22, 23, 25, 31, 32, or 45, all of them will work within this design.

We did a head-to-head review of the MCK vs. the Recover Tactical 20/20. Check out the results here.

Another major player within the conversion kit world is FAB Defense. It can be a bit harder to find their products out in the marketplace, but if you look long enough, you’ll find them.

Chief among their designs for the Glock is the KPOS Scout.

This thing packs up into a teeny little package and seems to be akin to an envelope -- everything on it folds up! You have a folding foregrip, folding stock, and flip-up sights.

It can accommodate a wide variety of ported Glock models, such as the Glock 17, 19, 22, 23, 25, 31, and 32.

For ease of long-term carry, it comes with a one-point tactical sling as well.

Like most conversion kits on the market, this contains a Picatinny rail upper for various attachments.

You will need to register this as an SBR with the ATF if you want to remain legal, though.

Final Thoughts

A conversion kit truly gives you a wide range of options when it comes to your Glock. Not to mention, it gives you quite an edge when it comes to long-range work with your pistol.

If you have some extra gun money laying around, consider grabbing one of these kits (and the required tax stamp if needed). I don’t think you’ll be disappointed.
