Key Features
- Lunar Finish — WHY IT MATTERS: The silver-gray anodized slide resists holster wear and corrosion better than blued finishes, and it stands out on the range for quick visual ID.
- Vertec Slim Grip with Replaceable Backstraps — WHY IT MATTERS: Shooters with smaller hands can finally get a solid purchase on a Beretta 92 without stretching for the trigger. Three backstraps let you dial in fit.
- Threaded Barrel (1/2×28) — WHY IT MATTERS: Ready out of the box for a suppressor or compensator. No gunsmithing needed — just screw on and shoot.
- Removable Front Sight — WHY IT MATTERS: Swap to fiber optic or tritium in under a minute without a press. That means faster target acquisition in low light.
- Duty-Proven Reliability — WHY IT MATTERS: This is the same platform that served U.S. military forces for decades. You can trust it to run with any quality 9mm ammunition.
Who It’s For
This pistol is for the shooter who wants a full-size 9mm that can pull double duty as a home defense tool and a competition pistol. It fits new shooters learning fundamentals with a DA/SA trigger, and experienced shooters who want a suppressor host without buying a separate barrel. If you value reliability over flash, and you appreciate a gun that ships ready to customize, this is your next purchase.
Pros & Cons
- Pro: Threaded barrel included at no extra cost — saves you $100–150 over buying aftermarket.
- Pro: Vertec grip makes the 92-series accessible to shooters with smaller hands.
- Pro: Removable front sight gives you options for night sights or fiber optics without a trip to the smith.
- Con: The DA/SA trigger has a learning curve. New shooters may struggle with the heavy first pull compared to a striker-fired pistol. Practice the transition.
- Con: The Lunar finish is eye-catching, but it can show carbon residue more than a black slide. Wipe it down after range trips.

The Beretta M9A4 gives you the most value for a suppressor-ready, full-size pistol. The Zev OZ9 and Agency Arms G19 are excellent, but you pay a premium for modularity and brand cachet. If you want a proven platform with a threaded barrel and adjustable grip out of the box, the M9A4 wins on price and versatility.
FAQ
What magazines does the Beretta M9A4 use?
It uses standard Beretta 92-series 15-round magazines. It also accepts 17-, 18-, 20-, and 30-round aftermarket mags from Mec-Gar or Beretta. The gun ships with two 15-round magazines.
Is the Lunar finish durable?
Yes. The Lunar finish is an anodized coating applied to the slide, which is harder than standard bluing or cerakote. It resists scratching and corrosion, but it will show carbon buildup more than a black finish. Clean it after each range session to keep it looking new.
Can I mount a red dot on the M9A4?
The M9A4 does not come with an optics-ready slide from the factory. You can have the slide milled by a gunsmith for a direct-mount red dot, or use a dovetail mount that replaces the rear sight. Many shooters choose to keep it with iron sights for reliability.
What holsters fit the M9A4 with a threaded barrel?
Look for holsters made for the Beretta 92 series with a threaded barrel or compensator cut. Brands like Safariland, Blackhawk, and Alien Gear offer options. The Vertec grip means any 92-series holster with an open bottom or barrel channel will work.
Is the M9A4 California compliant?
No. The M9A4 is not on the California approved handgun roster. It ships with standard-capacity magazines, so it is not legal for sale in California. Check your state laws before ordering.
