Description
KelTec has been building folding carbines since 2001, but chambering the SUB2000 Gen 3 in 10mm Auto takes the concept somewhere new. Out of a 16.15 inch barrel, 10mm picks up serious velocity over what any pistol can deliver, turning an already stout cartridge into a legitimate performer for the trail, the truck, or home defense. And because the whole thing folds in half to roughly 16 inches, it disappears into a backpack or range bag without a second thought.
What the Gen 3 SUB2000 Does Differently
The big story on the Gen 3 is the rotating forend. Older SUB2000s made you choose between mounting an optic and folding the gun. Now you twist the forend, fold the carbine, and your red dot stays right where you zeroed it. The handguard carries M-LOK slots along the sides with Picatinny rail up top and underneath, so lights, lasers, and hand stops all have a home. The 16.15 inch steel barrel wears 5/8×24 threading with a knurled thread protector from the factory, ready for a muzzle device or suppressor whenever you are. Adjustable sights and a three position stock round out a setup that fits a wide range of builds and body types.
Feeds From Glock 20 Magazines
This carbine runs on Glock 20 pattern mags, from the included 15 rounder up through extended sticks and even 50 round drums. For anyone already running a G20, that means one magazine pouch covers both guns. The simple blowback action keeps the design easy to maintain, and field stripping doesn't require tools.
A 10mm Folder That Earns Its Keep
At around 5.6 pounds unloaded, this tan model is light enough to carry all day and compact enough to stash almost anywhere. It's a natural fit as a camp gun, a backcountry companion in big animal country, or just a fun way to stretch 10mm out to carbine distances at the range. Few guns pack this much punch into this little space.

Frequently Asked Questions
Will the SUB2000 Gen 3 10mm run extended Glock 20 magazines and drums?
Yes. It feeds from standard Glock 20 pattern magazines, including extended stick mags and 50 round drums. That makes it a natural companion gun for G20 owners since everything cross loads between the two platforms.
Can I fold the SUB2000 Gen 3 with a red dot mounted?
You can, and that's the headline upgrade on the Gen 3. The rotating forend lets the carbine fold in half with an optic still mounted on the top rail, so your zero stays put. Folded, the whole package measures just over 16 inches.
What is the thread pitch on the SUB2000 10mm barrel?
The muzzle is threaded 5/8×24 and ships with a knurled thread protector installed from the factory. That's the common pitch for most 10mm and .40 caliber muzzle devices and suppressors, so finding an attachment that fits is easy.
How much velocity does 10mm gain from the 16.15 inch barrel?
Quite a bit. Depending on the load, you can see gains of several hundred feet per second over pistol length barrels, with some lighter bullets picking up 400 fps or more. That extra velocity gives 10mm noticeably more energy on target and flattens the trajectory at carbine distances.
