Beretta M9A4 Overland 9mm 5.1-inch 18rd Lunar
About this product
The Beretta M9A4 Overland 9mm 5.1-inch 18rd Lunar is a full-size, optics-ready 9mm pistol with a threaded barrel and trail-optimized features finished in Lunar Cerakote. This variant adapts Beretta's combat-proven M9A4 platform specifically for overlanding and field use, maintaining the double/single-action reliability that has defined the platform since its military adoption. The 5.1-inch threaded barrel and RDO-ready slide provide suppressor and optic compatibility out of the box, while the Cerakote Lunar finish offers superior corrosion resistance in harsh environments.
What is the Beretta M9A4 Overland used for?
The M9A4 Overland is designed for field carry, overlanding, and defensive use where environmental durability matters. Its 5.1-inch threaded barrel provides optimal velocity for 9mm defensive rounds while accommodating suppressors, and the tritium night sights maintain visibility in low-light conditions. The aluminum frame with polymer grips balances durability and weight at 34.2 ounces unloaded, making it suitable for extended carry compared to all-steel alternatives.
How does the Beretta M9A4 Overland compare to the Stevens 334 Rifle?
The M9A4 Overland serves entirely different applications than our Stevens 334 Rifle in .308 Win, with the Beretta offering rapid follow-up shots at closer ranges versus the bolt-action's precision at distance. While the Stevens provides superior long-range accuracy and stopping power, the M9A4 delivers faster target acquisition and higher capacity with its 18-round magazines. For overlanding scenarios requiring quick deployment against potential threats, the semi-automatic pistol format proves more practical than a full-sized rifle.
What does it weigh and what are the dimensions?
The M9A4 Overland weighs 34.2 ounces empty and measures 8.5 inches in overall length with a 5.1-inch barrel height of 5.6 inches. The width across the controls measures 1.5 inches at its widest point, accommodating most standard holsters while providing ample real estate for accessory mounting. Loaded with 18 rounds of 9mm, the total weight increases to approximately 42 ounces, still manageable for extended field carry.
Who is this NOT for?
The M9A4 Overland is not ideal for concealed carry or shooters seeking a compact defensive pistol. Its full-size frame and 8.5-inch length make concealment challenging compared to subcompact options like the SIG P365, and the 34.2-ounce weight becomes noticeable during all-day carry. Competitive shooters focused on speed shooting may also prefer lighter, striker-fired alternatives with shorter trigger resets.
What's in the box?
The package includes the pistol, two 18-round magazines, and a specialized overlanding kit with suppressor alignment tools and mounting hardware. The magazines feature anti-follower tilt design for reliable feeding, while the tool kit addresses common field maintenance needs specific to suppressed operation. All components are housed in a custom foam-cut case rated for environmental protection during transport.
Is the Beretta M9A4 Overland worth it at $1169?
At $1169, the M9A4 Overland justifies its premium for shooters requiring suppressor-ready capability and environmental durability in a proven platform. The included Cerakote Lunar finish alone represents a $200-300 value over standard finishes, while the optics-ready slide eliminates the need for aftermarket machining. Compared to similar offerings from SIG or HK, the Beretta maintains competitive pricing while offering superior out-of-the-box accessory compatibility.

Frequently asked questions
- Is it compatible with Beretta 92FS holsters?
- The M9A4 Overland fits most Beretta 92FS holsters, but the threaded barrel adds 0.6 inches of length that may require specific open-end designs. The Picatinny rail dimensions match the standard M9A4 pattern, ensuring light/laser compatibility across Beretta's ecosystem.
- Does it work with Trijicon RMR optics?
- Yes, the slide is pre-milled for Trijicon RMR footprint optics using the included mounting plate. Installation requires a torque wrench set to 15 inch-pounds per Beretta's specifications to maintain zero under recoil. The suppressor-height tritium sights provide lower-third co-witness with most micro red dots.
- How long does shipping take to Montana?
- FFL shipments to Montana typically arrive within 3-5 business days via UPS or FedEx with signature confirmation required. All firearms ship within 24 hours of FFL verification, with tracking provided via email notification. Rural deliveries may add 1-2 additional days depending on local carrier routes.
- Can I return it if the finish doesn't meet expectations?
- Cerakote finishes are not eligible for return due to cosmetic variation, but functional defects are covered by Beretta's 3-year warranty. The Lunar finish is applied to a minimum thickness of 1.2 mils for corrosion resistance, with color consistency varying within industry standards. Contact Beretta directly at 800-636-3420 for warranty claims.
