If you think an AR-15 pistol in 5.56 is kinda rowdy, how about an AR-10 in .308? I’ve been fooling about with one for the past few months (when I can get ammo).

Behold, the Diamondback DB10P, with a 13.5-inch barrel.

DB10

Equipped with an adjustable Gear Head Works Tailhook Mod 2 stabilizing brace, the DP10 is 31 inches long overall with the hook extended all the way and hits the scales at 7.8 pounds.

Playing with Jelly

It is not rocket science. Longer barrels give you more complete propellant combustion which translates to more velocity imparted to the projectile. The more velo, the more energy is carried by the projectile on the impact and the higher ballistic performance. In short, whittle the barrel down and you sacrifice some performance. By way of thinking, the optimal performance for NATO 5.56mm ball, such as M855, is wrung through a 20-inch barrel.

With that in mind, I wanted to check and see just how much velocity dumped by running a 7-inch barrel out of a DB15 I have been testing for the past few weeks.

This thing.

For reference, the Winchester 55-grain 5.56 NATO FMJ rounds I chose for the bulk of our reliability testing have a listed 3,270 fps muzzle velocity generating 1,305 ft./lbs. muzzle energy. We found that, out of the 7-inch DB15, an average across five rounds hit closer to 2,240 fps, which, using the standard bullet energy formula, translates to something like 619 ft./lbs., or a loss of about a third of its velo and half of its energy.

How effective is that? Well, in 10% gel, the FBI recommends 12-to-18 inches of penetration to be considered an effective self-defense round. In our tests with a 16-inch block of Clear Ballistics 10% gel, I found that every round of a 7-shot test string of Winchester 55-grain FMJ penetrated the entire block and left a significant channel in its wake. 

Food for thought. Now to test some Gold Dots and the like to see how they expand.

An 8-pound pistol

So for the past few weeks, I have been fooling around with a T&E DB15 pistol. Featuring a 7-inch barrel, it is a fairly compact blaster and I have to admit that the KAK Flash Can and Gearhead Works Tailhook is growing on me.

While right out of the box, the 23-inch long 5.56 NATO handgun weighs just 4.53-pounds, I have added a Sig Sauer Romeo 5 red dot, a 600-lumen Streamlight and a Magpul D60 drum to it, bringing its loaded all-up weight with spare batteries (in the MOE grip) and boolits of 8.7-pounds.

Nice. For reference, the total cost as shown with all accessories is still under $1K.

So I have been carrying the Beretta 92X Compact for 2 months…

I’ve have been shooting and carrying one of Beretta’s newest versions of their iconic Model 92, the 92X, and have a few things to report.

While the standard/full-sized 92X uses a 4.7-inch barrel to produce an 8.5-inch long handgun that tips the scales at 33.4-ounces while unloaded, the smaller Centurion is a more Commander-style offering with a shorter 4.25-inch barrel which boils down to a 7.75-inch overall length.

Going even shorter, the 92X Compact has the Centurion-length slide and barrel on a shorter frame (5.25-inches high, versus the standard 5.4-inch) to produce a handgun more suited for concealed carry. This puts the Compact in roughly the same class, size-wise, as guns such as the Glock G19, Sig Sauer P229, and S&W M&P M2.0 Compact.

I have carried it for over 400 hours and ran 2,000 rounds in it drawn from a selection of loads from Winchester, Federal, CCI (Blazer), Wolf, and PMC in weights between 115- and 147-grain with a mix of various training and self-defense ammo in standard commercial, military, and +P velocities.

Long story short: one malfunction in shooting, some belly skin lost in carry. Other than that, not bad. Not bad at all.

In the end, the 92X gives the modern shooter a reliable handgun that stands on 40+ years of legacy while having a lot of features– DA/SA hammer-fired action, all-metal construction, slide-mounted safety/decocker– that you aren’t going to find on the average plastic fantastic.

Further, it does it all in three available sizes with a ton of aftermarket support. The 92X series may not get people to drop their polymer striker-fired handguns, but it does give those who are familiar with, or prefer, the 92 families a more contemporary pistol that is both fun to shoot and dependable.

I got my hands on one back in August and have been kicking it around for a few months to see how it held up.
