Key Features
- Optics-Ready Slide: The slide is pre-milled for a wide range of red dots — mount your RMR or Holosun without sending the slide out. Why it matters: you get faster target acquisition without the wait or gunsmith fees.
- Threaded 5.1-Inch Barrel (1/2×28): Factory-cut threads let you attach a suppressor or compensator instantly. Why it matters: this is one of the few production duty pistols that ships ready for suppressed shooting.
- G-Model Decocker-Only Controls: The G variant eliminates the manual safety, leaving a simple decocker that drops the hammer safely. Why it matters: no fumbling with a safety under stress — just draw, decock, and shoot.
- Dovetailed Tritium Night Sights: Three-dot tritium inserts glow in low light, and the rear sight is dovetailed for easy windage adjustment. Why it matters: you retain iron-sight capability even if your optic fails.
- 10-Round Magazine: Ships with two 10-round mags for compliance in restricted states, but accepts all standard 92-series magazines. Why it matters: you can use the same mags as your existing Beretta 92.
Who It’s For
This pistol is built for duty carriers, competition shooters, and home defenders who want a proven NATO-tested platform with modern upgrades. If you run a suppressor or red dot and need a reliable full-size 9mm that works from the first round, the M9A4 G fits.
Pros & Cons
- Pro: Factory optics cut with multiple plate options — no aftermarket machining needed.
- Pro: Threaded barrel included at no extra cost; saves $150–200 over buying a separate barrel.
- Pro: G-model decocker is intuitive for shooters transitioning from DA/SA pistols.
- Con: The 10-round magazine capacity is limiting for states without restrictions; you’ll likely want to pick up 15- or 17-round mags separately. Per Beretta specs, standard-capacity mags are available but not included in this SKU.

FAQ
Does the Beretta M9A4 G come with suppressor-height sights?
It ships with standard-height tritium night sights. If you mount a red dot, you may need taller sights for a lower 1/3 co-witness; aftermarket options are available from Dawson Precision and Trijicon.
Can I use standard Beretta 92 magazines in this pistol?
Yes — the M9A4 G accepts all 92-series magazines, including 15-, 17-, 18-, and 20-round mags. The 10-rounders are for restricted states only.
Is the barrel threaded for a suppressor or compensator?
Yes, the 5.1-inch barrel has standard 1/2×28 threads, compatible with most 9mm suppressors and compensators. A thread protector is included.
What optics fit the M9A4 G slide?
The slide uses interchangeable plates. Beretta includes plates for Trijicon RMR, Holosun 407C/507C, Leupold DeltaPoint Pro, and Shield RMSc footprints. Check the included manual for plate part numbers.
Is this the same as the military M9?
Not exactly. The M9A4 G has an optics-ready slide, threaded barrel, and Cerakote finish, while the M9 has fixed sights and a non-threaded barrel. The G-model decocker is also different from the M9’s safety/decocker.
