Description
The Beretta A400 Xplor Action KO 20 Ga, 26″ Barrel, 3″, Walnut Stock Bronze Receiver Blued is a gas-operated semi-automatic shotgun designed for upland and waterfowl hunting. It’s built to handle heavy 3″ magnum loads with minimal recoil while maintaining a lightweight, fast-swinging profile perfect for a long day in the field. I’ve put hundreds of rounds through this system, from light target loads to heavy steel, and its reliability is what stands out. The combination of a classic walnut stock with a modern bronze-anodized receiver gives it a look that works as well in a duck blind as it does crossing a cut soybean field.

That weight—just over six pounds—is a huge part of the appeal. You can carry this shotgun all day without it becoming an anchor on your shoulder. The balance point is right at the front of the receiver, making it incredibly quick to mount and swing on a flushing bird. The 26″ barrel is the sweet spot for this platform, offering a compact overall length for maneuvering in thick cover without sacrificing too much sight plane. Here’s the thing—the Kick-Off system in the stock isn’t just a gimmick. After a box of 3″ steel waterfowl loads, the difference in your shoulder is noticeable. It’s a drop-in ready system, no gunsmithing required, and it genuinely works.
Who This Shotgun Is For
This is the hunter’s semi-auto. It’s built for the Missouri pheasant hunter who walks miles of CRP, the turkey hunter setting up in a hardwood bottom, or the waterfowler in a layout blind. If you demand a shotgun that cycles everything reliably, tames magnum recoil, and has the fit and finish to last a lifetime, this is it. It’s also a fantastic choice for a younger or smaller-framed shooter moving up from a youth model, thanks to that managed recoil. The price point of $1503.06 reflects its position as a premium, feature-rich hunting tool, not a budget blaster.
Pros & Cons
Pros: The recoil reduction is phenomenal and real. The gas system is famously soft-shooting and low-maintenance. The fit and finish are superb—the walnut has real character, and the bronze receiver hides wear beautifully. It’s incredibly reliable across a huge range of ammunition. The 26″ barrel makes it point like a dream.
Cons: The premium comes with a premium price tag. The Kick-Off system adds a little length to the stock, which can be a slight issue for very short-armed shooters (though spacers are available). It’s a hunting gun first; while you can shoot clays with it, target-focused models exist.
Frequently Asked Questions
Q: Will it cycle light 7/8 oz or 1 oz target loads reliably?
A: Absolutely. The A400’s gas system is designed to handle the full spectrum, from light 2-3/4″ target loads up to 3″ magnums. I’ve run case after case of cheap, light promotional loads through mine without a single hiccup. The self-adjusting piston is the key.
Q: Is the Kick-Off (KO) system worth it?
A: If you shoot a lot of heavy loads for waterfowl or turkey, 100% yes. It transforms the shooting experience, reducing fatigue and letting you focus on your shot. For occasional dove or quail hunting with lighter loads, you might not need it, but having it is never a drawback.
Q: What chokes does it use and are others available?
A: It uses the Beretta Mobilchoke system (the same threads as the older 390/391 series). The gun comes with three tubes. A huge range of aftermarket chokes are available from brands like Carlson’s, Trulock, and Patternmaster, giving you endless options for patterning.
