What Is the Shield Arms SA-9 Gen 2?

The SA-9 is a folding 9mm AR pistol built on our patented Folding Lower Receiver. It runs Glock® double-stack 9mm magazines, folds from 23.5" to 13" at the receiver with no hinge adapter, and locks the bolt back on an empty magazine. It's a closed-bolt blowback design with a 7.5" threaded barrel, an SB Tactical SBA3 brace and a billet 7075-T6 lower made in Bigfork, Montana. It ships with two 20-round Glock® 19 magazines and a sling.

  • Caliber: 9mm, 7.5" barrel threaded 1/2x28
  • Length: 23.5" open, 13" folded
  • Magazines: Glock® 17, 19, 26 and 33-round
  • In the box: (2) Glock® 19 mags with +5 extensions, sling
SA-9 Gen 2

13 Inches Folded. Runs Your Glock® Mags.

Most folding ARs bolt a hinge on behind the receiver. The SA-9 folds at the receiver itself, on our patented FLR, so it closes to 13 inches with no adapter in the way. That's short enough for a backpack, a truck console or a case that doesn't announce what's inside.

It feeds from the same Glock® double-stack 9mm magazines your pistol uses, so one set of mags and one caliber covers both. Gen 2 adds a last round bolt hold open and a redesigned magazine release for more positive magazine engagement.

Questions

SA-9 Gen 2 FAQ

Which magazines does it take?

Glock® double-stack 9mm magazines: the 17, 19, 26 and 33-round. Two Glock® 19 magazines with our +5 extensions come in the box, 20 rounds each.

What changed in Gen 2?

Gen 2 adds an integrated last round bolt hold open, a redesigned magazine release for more positive engagement, and updated styling.

How is the fold different from a folding adapter?

An adapter adds a hinge behind the receiver. On the SA-9 the fold is machined into the lower receiver itself, on our patented FLR. See how the FLR works.

Can it fire while folded?

No. Unfold it and lock the receiver before firing. The fold is for carry and storage.

Is it suppressor ready?

Yes. The barrel is threaded 1/2x28. Remove the A2 flash hider and mount a 9mm suppressor with matching threads.

What ammunition does it run?

It's set up for standard 9mm in 115, 124 and 147 grain. The buffer has removable steel weights if you need to tune it for a specific load or a suppressor.

Can I add an optic?

Yes. The upper has a flat-top Picatinny rail for any standard AR optic mount, and the 6" handguard takes M-LOK accessories.

How long until it ships?

Every SA-9 is built to order. Plan on 7 to 10 business days after your order is placed and we receive your FFL's license.

Is it a pistol or an SBR?

It's built and sold as a pistol, with a 7.5" barrel and an SBA3 pistol brace. Federal, state and local rules on braced pistols can change, so check the current rules where you live.

Can I pay over time?

Yes. Credova financing is available at checkout.
