KELTEC SUB2000 Gen 3 10mm Glock 20 Grip OD Green 15rd

I’ve had a soft spot for the Kel-Tec SUB2000 ever since the first generation hit the market, and this Keltec SUB2000 Gen 3 10mm Glock 20 Grip OD Green 15rd is hands-down the best version yet. If you already carry a Glock 20 for hiking or home defense, this carbine lets you share magazines — a huge plus when you’re packing light. At $549.99, it’s a solid value for a folding, optics-ready 10mm that tucks into a backpack or range bag.

Key Features

• Rotating Forend with Optics Compatibility — Why it matters: older SUB2000s forced you to remove a red dot before folding. This Gen 3 rotates the forend 90 degrees so your optic stays zeroed and the gun folds flat. That’s a game-saver for truck or pack storage.
• Threaded Steel Barrel (1/2×28) — Why it matters: you can mount a muzzle brake, compensator, or suppressor without a gunsmith. For 10mm, a brake tames the snap, and a can makes it hearing-safe for the range or home defense.
• Three-Position Adjustable Stock — Why it matters: length of pull adjusts from 13.5 to 15 inches, so it fits shooters from 5’2″ to 6’4″. My wife and I both shoot it comfortably without swapping parts.
• Glock 20 Magazine Compatibility — Why it matters: if you already own a Glock 20, you’ve got a stack of mags that work here. One ammo type, one magazine platform, less to remember under stress.
• Lightweight at 5.6 Pounds — Why it matters: you can carry this all day on a sling without fatigue. It’s lighter than most 9mm carbines, and 10mm hits harder than .357 Magnum out of a rifle barrel.

Who It’s For

This carbine is built for the shooter who wants a compact, packable rifle that shares ammo and magazines with their Glock 20 sidearm. It’s ideal for backcountry hikers, truck gun owners, and home defenders who want 10mm’s extra energy without the weight of a full-size rifle. New shooters will appreciate the low recoil (for a 10mm) and simple manual of arms.

Pros and Cons

• Pros: Folds to 16 inches for storage, accepts Glock 20 mags, threaded barrel for suppressors, optics-ready out of the box, three-position stock, OD Green looks great, affordable price.
• Cons: The polymer forend can feel a bit flexy under heavy pressure — it’s not a free-float handguard. Also, the factory trigger is about 6.5 pounds with some creep. Per Kel-Tec specs, the trigger is not user-serviceable without aftermarket parts.

FAQ

Will the Kel-Tec SUB2000 Gen 3 accept Glock 20 magazines with extended baseplates?

Yes, it will accept standard Glock 20 magazines (15 rounds) as well as factory extended magazines (such as the 22-round and 33-round options). However, aftermarket baseplates that add significant thickness may not fit the magazine well without modification. Stick with OEM Glock or Kel-Tec recommended mags for reliable feeding.

Can I mount a suppressor on the threaded barrel without losing the folding ability?

Yes, the barrel is threaded 1/2×28 and the rotating forend allows the carbine to fold with a suppressor attached — as long as the suppressor diameter does not exceed the forend’s inner clearance (about 1.5 inches). Most pistol-caliber cans like the SilencerCo Osprey or Rugged Obsidian 9 will clear. Always test fit before relying on it.

Does the OD Green model have the same three-position stock as other Gen 3 colors?

Yes, all Gen 3 SUB2000 models — including the OD Green variant — feature the same three-position adjustable stock. The adjustment is done by pressing a button on the rear of the receiver, and it clicks into place at 13.5, 14.25, and 15 inches length of pull.

What is the warranty on this carbine?

Kel-Tec provides a limited lifetime warranty to the original owner. If you have any manufacturing defects, they’ll repair or replace the firearm. Keep your original receipt. Per Kel-Tec’s website, warranty transfers are not allowed, but they still offer repair services for a fee to second owners.
