GLOCK 43X Hush Puppy, 3.92″ Threaded Barrel, Black Cerakote by Shark Coast Tactical, Suppressor Height Sights, Sup PK 407K

Product Description

The Glock 43X Hush Puppy is a complete suppressed-pistol package: a Glock 43X SLIMLINE 9mm with a 3.92-inch threaded barrel, suppressor-height sights, a Holosun 407K red dot on an optic-cut slide, black Cerakote by Shark Coast Tactical, and a suppressor. It is the shortest path from wanting a suppressed carry-size 9mm to owning one, because every part of the system was selected to work together.

Most people who go looking for a suppressed Glock 43X end up assembling it themselves: buy the pistol, source a threaded barrel, replace the sights so they clear the can, add an optic, then shop for a suppressor separately. This package removes all four of those decisions and the fitment risk that comes with them.

What It Takes to Suppress a Glock 43X

Three things have to be true before a Glock 43X will run a suppressor properly, and a stock 43X has none of them.

First, the barrel has to be threaded. The factory 43X barrel is not, so it has to be replaced. Second, the sights have to be tall enough to clear the suppressor body, or you lose your sight picture entirely the moment the can is mounted. Third, you need the suppressor itself, which is a Form 4 item on its own timeline. This package covers all three.

A subcompact slide also has less mass to work with than a full-size gun, so pairing the right can with the right pistol matters more here than it does on a Glock 19 or 17. That pairing is the reason to buy the package rather than assemble it piece by piece.

Suppressed Glock 43X for Carry and Home Defense

A suppressed 9mm is not quiet the way movies suggest, but it is hearing-safe in most configurations, and indoors that is the whole argument. An unsuppressed 9mm fired in a hallway will damage your hearing permanently in one round.

The 43X frame is the reason this configuration appeals to carriers rather than just range shooters. It is a slim, full-grip pistol that hides well, so the host gun is one you would carry anyway. If you are still choosing between models, our Glock 43 vs Glock 43X comparison covers the grip and concealment trade-off, and our guide to the best suppressor for a Glock 43X walks through the can options if you would rather build it yourself.

Frequently Asked Questions

Q: Can you put a suppressor on a Glock 43X?

A: Yes, but not on a stock one. A Glock 43X needs a threaded barrel and suppressor-height sights before it will run a can usefully, because the factory barrel is unthreaded and the factory sights disappear behind a suppressor. This Hush Puppy package includes the threaded barrel, the taller sights and the suppressor together.

Q: Does this Glock 43X package include the suppressor?

A: Yes. The suppressor is part of this package, which is why the purchase goes through an ATF Form 4 rather than a normal handgun transfer. Call 817-393-4000 and we will confirm the exact can in the package before you commit.

Q: Do I need a tax stamp to buy a suppressed Glock 43X?

A: Yes, an approved ATF Form 4 is required before you can take possession of the suppressor. The stamp itself is $0 under the One Big Beautiful Bill Act. The pistol portion transfers on a standard Form 4473 like any other handgun.

Q: Why does a suppressed Glock 43X need suppressor-height sights?

A: A suppressor body sits directly in front of and above the muzzle, and it blocks standard-height iron sights completely. Suppressor-height sights are tall enough to see over the can, so you keep a usable sight picture with the suppressor mounted and still co-witness with the red dot.

Q: Is a Glock 43X too small to run suppressed?

A: No, but the pairing matters more than it does on a full-size pistol. A subcompact slide has less mass and a shorter cycle than a Glock 19 or 17, so the suppressor and the pistol have to be matched to keep the gun cycling reliably. That matching is the reason to buy a built package rather than assemble parts.

Q: How long does the Form 4 take, and can I shoot the pistol while I wait?

A: You take possession of the suppressor only after the ATF approves the Form 4; see our NFA wait times guide for current approval times. The pistol side is a normal handgun transfer, so ask us how we handle the split at pickup — call 817-393-4000 and we will walk you through it.
