Diamondback DBX – Dual Piston Pistol

Diamondback DBX Review on Range

Diamondback Firearms announced the new DBX pistol at SHOT Show 2020. The new gun is chambered for the 5.7×28 cartridge and has a variety of interesting features that might grab your attention.

So, let’s not dally about and jump right in.

General Information

The new Diamondback DBX is in the general style of an AR pistol, but it should be readily apparent that it is not as simple as that.

Diamondback Firearms manufactured this semi-automatic pistol as a locked-breech design with a dual-piston gas system. I’m looking forward to getting some time with this gun to see how the system is designed.

Unlike some of the alternatives, this is a bottom feeder with the magazines inserting in the AR-standard position. The gun runs on FN Five-seveN 20-round magazines. However, the company has also announced that a second gun that will feed from the Ruger-57 pattern magazines will also be released. One magazine is included.

The 8″ barrel is threaded. It comes fitted with the company’s new DBX muzzle device.

Up front, the forend has M-LOK attachment points on the left, right and bottom for a wide range of accessories. Included with the gun is a Magpul handstop kit. For a gun this short, I like that the company includes this as a standard accessory.

Diamondback includes a side folding arm brace with the pistol. It attaches to the Picatinny rail on the butt end of the gun.

What Gives?

The new Diamondback DBX is one of several new guns recently announced for the 5.7×28 cartridge. Additionally, there have been some new ammo additions like the Speer Gold Dot self-defense load.

Why the sudden surge of interest in this cartridge?

I don’t have any inside information, but I believe all three guns were developed independently. This suggests that the sales and design teams at three different companies reached the same conclusion on the market data they had. That conclusion: there is enough market demand for guns chambered for the cartridge to make the projects financially viable.

So, what happens when three companies move to satisfy the same demand?

Diamondback DBX LEft Side

In this case, I believe it will work out well for all of the companies.

Starting with the Ruger-57, there has been a lot of discussion surrounding the cartridge. When CMMG announced its own rifles and pistols (along with AR conversion kits) in 5.7×28, even more people took notice. With a third company jumping into the pool, it will make a lot of people ask “What am I missing?”

Will those people turn into buyers? I think a lot of them will. With the support of premium ammunition for self-defense, target shooting and small game hunting, the cartridge suddenly has a life I did not expect to see.

I look forward to a Diamondback DBX review, but what do you think? It is hard to carry concealed – after all, you can’t slip it into a Ruger-57 holster, but for a home defense weapon, it might be a great choice. Are you interested in this cartridge and/or pistol?

Ruger-57: New 5.7×28 Pistol

Ruger-57 Pistol

I like it when companies do unexpected things. Sometimes these outside-the-box ideas change the industry while other times they simply become a curiosity. Either way, it keeps things interesting.

The Ruger-57 is one of those unexpected pistols.

In the days leading up to the SHOT Show, Ruger is rolling out its new products for 2020. Yesterday, the company announced the Lite Rack LCP II. Today, the latest is a handgun chambered for the 5.7×28 cartridge.

Let’s take a look at what this new gun offers.

Quick Note

This gun has been selling out as soon as they hit the shelves of the local dealers. Here are a few online sources you can check for the gun. Purchases through those sites are affiliate links and help pay my bills.

Gun Design

The new Ruger-57 is a full-size pistol with a polymer frame. It has a barrel just short of 5″ and a modest weight of 24.5 ounces.

Ruger-57 Side View

It is a semi-automatic, blowback design. Ruger designed the hammer-fired gun with a 1911-style thumb safety. The safety is ambidextrous for ease of use regardless of which hand grips the pistol.

A front fiber optic sight with a fully adjustable blacked-out rear sight is standard. The gun is red dot ready. Ruger sells multiple mounting plates for the addition of an optic like the Burris FastFire and Vortex Venom.

Standard magazines hold 20 rounds. However, the company also offers limited capacity 10-round magazines for shooters who live in less-free states.

The 5.7×28 Cartridge

There is a good chance that some of my readers are not familiar with the 5.7×28 cartridge.

5.7x28 Ammunition for Ruger-57

That’s understandable as the cartridge has never secured a large part of the firearms market. Nevertheless, it is a caliber that offers a blend of low recoil, high velocity and the reliability of a centerfire round.

In general terms, it is a cartridge with a bottleneck case and a bullet with a diameter of 0.224″ (5.7mm.) Bullet weights range from about 20 grains to about 50 grains. The cartridge could be thought of like a thinner, shorter .221 Fireball though I have no information that suggests the Fireball directly influenced the 5.7×28 design.

Lightweight projectiles tend to make for less recoil and increased velocities. In my own testing, for example, I found the SS197 load with a 40 grain Hornady V-Max bullet averaged 1,683 fps from a 4.8″ barrel.

FN Herstal developed the round in response to a NATO request for a small arms cartridge that could be fired from a pistol and personal defense weapon (PDW) and could penetrate body armor. Although the cartridge and companion firearms were never adopted in any significant quantity by military units, the cartridge and guns have found use in law enforcement and sporting contexts.

Other than the new Ruger-57, there are few companies manufacturing firearms chambered for this cartridge. FN builds the Five-seveN pistol and PS90 rifle chambered for the 5.7×28. There are also several smaller companies that make or previously made specialty guns for the round including the AR-57 and Masterpiece Arms MPA 57.

Speer Gold Dot 57x28 Ammo

While ammunition selection is fairly limited, Speer introduced a new Gold Dot defensive round for the 5.7×28 at the same time Ruger released this new pistol.

The Speer load uses a 40-grain bullet and will be sold in boxes of 50 rounds. The MSRP is about $1/round but street prices are expected to be about $35-39 for a box of 50.

Holster Options

For self-defense, predator control or just plinking on a camping trip, there is a good chance you will need a holster for your new Ruger-57. Fortunately, Ruger had the good sense to work with a number of companies to ensure there would be carry rigs available at launch.

Final Thoughts

I have a positive first impression of the new Ruger-57.

Ruger-57 Review

As I always say, the proof will be in the shooting. Even so, I am intrigued by this gun and have high expectations for its performance and the amount of fun it can provide.

The guns are not cheap by Ruger standards, but it is an all-new design and there are costs associated with that. Compared to the FN Five-seveN, the pistol is significantly less expensive – by more than $600. That will definitely bring more shooters to the 5.7×28 niche. I hope that means we will see more ammo made for it as well.

MasterPiece Arms 5.7×28 SBR

MPA 5.7x28 SBR

MasterPiece Arms is now making a short barrel rifle (SBR) version of their 5.7×28 gun.  The new SBR has a threaded 8″ barrel for the included muzzle brake, or for the MPA Suppressor (which is shown in these photos but does not come with the gun).  Yes, all NFA rules do apply.

The MPA57SST-SBR (aka MasterPiece Arms 5.7×28 SBR) comes outfitted with an MPA short aluminum quadrail and a Strike Industries foregrip.  Based on the photos, the foregrip appears to be the “Cobra Tactical” that normally retails for $25.
