    GLOCK 43X Hush Puppy w/ Holosun 407K & Compact Model 2 Suppressor (FDE, Threaded): Turnkey Suppressed Slimline Setup

    GLOCK 43X Hush Puppy w/ Holosun 407K & Compact Model 2 Suppressor: A Turnkey Suppressed Slimline Package

    Introduction

    The GLOCK 43X Hush Puppy 9mm Sub-Compact Pistol w/ Holosun 407K, 3.92in 1/2x28 Threaded Barrel, FDE Cerakote, 10rd, Compact Model 2 Suppressor is built for shooters who want a complete, suppressor-ready micro-compact system—already configured with an optic, suppressor-height sights, a threaded barrel, and a purpose-driven slide-lock lever intended for specialized suppressed operation.

    Unlike “assemble-it-yourself” suppressed carry/range builds, this package is meant to be a coherent system out of the box: slimline ergonomics, modern dot capability, and a compact 9mm suppressor that prioritizes concealment and reduced report. The Flat Dark Earth Cerakote finish applied by Shark Coast Tactical adds an additional layer of corrosion and wear resistance while delivering a distinct duty-ready aesthetic.

    Key Features and Specifications

    Below are the key technical elements and what they mean in real use.

    Pistol platform (Slimline 43X-based configuration)

    • Caliber: 9mm Luger
    • Action: Semi-automatic, striker-fired (GLOCK-pattern)
    • Frame: Polymer
    • Magazine capacity: 10 rounds (factory configuration for the slimline pattern)

    Suppressor-ready barrel setup

    • Barrel length (package configuration): 3.92" threaded barrel (per provided product context)
    • Thread pitch: 1/2x28, the most common U.S. standard for 9mm pistol suppressor mounting
    • Practical benefit: 1/2x28 compatibility dramatically simplifies suppressor selection, piston selection (if used), and accessory support across the broader U.S. suppressor ecosystem.

    Optics-ready slide & included red dot

    • Optic included: Holosun 407K
    • Reticle: 6 MOA dot (typical HS407K configuration)
    • Notable features (Holosun 407K family): long battery life, Shake Awake motion-activation, and compact “K footprint” sizing optimized for slim pistols. (For model-family specs, see Holosun’s HS407K product page.)

    Optic cut / footprint compatibility (package claim)

    • Product context indicates a MOS-K optic cut with compatibility for:
      • Holosun 507K/407K
      • Holosun EPS
      • RMSc-pattern optics

    Because footprint terminology is often used inconsistently across the industry, the practical takeaway is this: the slide is intended for common micro-optics used on slimline carry pistols, with the included Holosun 407K being a “native fit” for the intended setup.

    Suppressor-height sights

    • Feature: Tall iron sights designed to provide a usable sight picture over the suppressor body.
    • Benefit: You retain an immediate “dot + irons” aiming solution even when the suppressor is mounted, and you preserve a backup sighting system should the optic be occluded, damaged, or have a dead battery.

    Finish & durability

    • Finish: FDE Cerakote by Shark Coast Tactical (per product context)
    • Benefit: Cerakote can enhance corrosion resistance and holster-wear durability compared to bare finishes, especially for users who carry daily, sweat heavily, or operate in humid/coastal environments.

    Included suppressor and slide-lock lever (the ‘Hush Puppy’ concept)

    • Suppressor included: Hush Puppy Project Model 2 (Compact) suppressor (package states “Compact Model 2 suppressor”)
    • Included control: Hush Puppy slide lock lever

    The defining “Hush Puppy” concept is the slide-lock feature: when engaged, it reduces the noise and gas associated with the slide cycling and the ejection port. Conceptually, this can make suppressed 9mm substantially quieter at the shooter’s ear and can change how the pistol behaves (more like a manually-cycled system for that shot string).

    Model 2 pricing reference (manufacturer listing)

    • Hush Puppy Project lists the Model 2 Silencer with a displayed “Now” price of $799 on their site. This may not reflect your package price (and your listing shows $0 / MSRP $0), but it is useful as a current manufacturer reference point for the suppressor component.

    Practical Applications

    This package is at its best when you want a small-footprint pistol that can shift between “normal 43X handling” and “suppressed, low-blast, low-flash” roles.

    1) Discreet range setup with maximum suppression for size A compact 9mm can on a slimline pistol is an excellent way to reduce perceived blast and make training more comfortable—especially when shooting on shorter indoor ranges or under covered bays where concussion is amplified.

    2) Suppressed home-defense (with realistic expectations) A suppressed handgun can help protect hearing in an emergency, reduce flash, and improve communication in a confined space.

    • Important note: “Hearing safe” is ammunition-, suppressor-, and environment-dependent. Suppressors reduce risk; they don’t eliminate it.

    3) Training value: dot + suppressor + tall irons The included optic and suppressor-height sights let you practice:

    • dot acquisition under recoil
    • target transitions with a compact window optic
    • confirmation of mechanical offset and holds at close distances

    4) Special-purpose suppressed operation with slide lock Where legal and appropriate, the slide lock lever is the unique differentiator: by preventing slide cycling during firing (when engaged), it can reduce the noise signature and eliminate the “clack” of reciprocation. This is niche by design—yet it’s exactly what many buyers want when they seek out a “Hush Puppy” configuration.

    Expert Analysis

    From a system-design standpoint, the standout strengths of this package are coherence and compatibility.

    Why this configuration makes sense

    • 1/2x28 threads keep suppressor mounting straightforward for most U.S. 9mm pistol suppressor ecosystems.
    • The Holosun 407K is a proven micro-dot form factor for slim pistols; a 6 MOA dot is fast to pick up and well-suited to defensive-speed shooting.
    • Suppressor-height sights are not an afterthought; they’re critical for usability once a can is installed.
    • The slide-lock lever is a genuine capability increase for users specifically chasing the “quietest possible” suppressed pistol behavior.

    Ammo and reliability considerations (what experienced users plan for)

    • Subsonic ammunition (commonly 147gr and heavier, depending on load) typically yields the best suppressed results by avoiding the supersonic crack.
    • Compact suppressors can increase backpressure and change cycling dynamics. The slide-lock lever can change the operating mode when engaged, but you should still expect to verify function with your chosen ammo.

    Ergonomics and concealment reality check A slim pistol with a micro-dot can conceal very well. Adding a suppressor makes concealment a different problem entirely—most users treat the suppressor as a “staged” accessory (nightstand, bag, range) rather than an always-on carry component.

    NFA compliance (process overview) Suppressors remain regulated under the National Firearms Act (NFA), and transfer typically involves an ATF Form 4 process. As of January 1, 2026, multiple industry/advocacy sources indicate the federal transfer tax was reduced to $0 for suppressors, while the Form 4 and background check process remains (always confirm current requirements for your state and situation before starting paperwork).

    Conclusion

    If your goal is a ready-to-run suppressed slimline pistol without chasing parts compatibility, the GLOCK 43X Hush Puppy 9mm Sub-Compact Pistol w/ Holosun 407K, 3.92in 1/2x28 Threaded Barrel, FDE Cerakote, 10rd, Compact Model 2 Suppressor is a compelling “complete system” approach.

    You’re getting the key elements that typically cause friction in suppressed handgun builds—threaded barrel specs, suppressor-height sights, and optic integration—plus the distinctive slide-lock lever capability that defines the Hush Puppy concept. For buyers who want a compact, modern, suppressor-optimized package with a micro red dot already included, this is exactly the kind of turnkey setup that minimizes guesswork and maximizes time on the range.
