The 10mm Auto cartridge has made a resurgence during the last decade and with good purpose. The ten provides you .357 Magnum-like energy in a rimless .40 caliber cartridge supposed for higher-capacity semi-auto handguns. The .357 in a lever motion carbine configuration has lengthy been espoused for medium sport searching and private protection with out the recoil of bigger rifle cartridges. However what a couple of 10mm carbine? Enter the Grand Energy Stribog SP10A3.
The 10mm as a Carbine Cartridge
The 10mm Auto is a wonderful pistol cartridge, however it has been traditionally underutilized as a PCC spherical. 9mm Luger is, by far, the preferred, and second to it’s .45 ACP. The ten provides greater velocity and higher penetration than both, which has given it some favor amongst handgun hunters. Setting it up in a carbine is the following logical step.
When the FBI first adopted the 10mm Auto in 1990 as their subsequent handgun cartridge, a restricted variety of MP5 submachine weapons have been produced in that caliber as an alternative of the usual 9mm. The short decline in curiosity killed the 10mm carbine idea. The concept has seen a resurgence because the virtues of the ten are rediscovered. Ruger not too long ago launched their LC Carbine in 10mm. World Ordnance of Sarasota, Florida has not too long ago begun importing the Grand Energy Stribog SP10A3, a braceable pistol now up-gunned to 10mm Auto.

The Grand Energy Stribog 10mm: Quirks and Options
The Stribog is a novel Slovak-designed 9mm submachine gun. It has turn out to be standard within the States as a cheap semi-auto pistol. The SP10A3 is similar handgun however in 10mm Auto.
The Stribog is blowback operated and contains a polymer decrease receiver with an aluminum-backed set off group, in addition to an integral aluminum higher and M-Lok handguard. It comes with an 8-inch barrel with 1/2×28-inch threads. The barrel is fastened and sits low simply above the decrease receiver, whereas a nonreciprocating charging deal with rides above it.
The again of the receiver is capped with a Picatinny railed polymer inventory adapter that may be saved as is or eliminated for a stabilizing brace. In contrast to the fair proportion of PCCs available on the market, the Stribog SP10A3 is as absolutely ambidextrous because it could possibly be. It contains a double-sided security selector north of the pistol grip inthe acquainted AR-15 trend. The charging deal with is reversible so it may be manipulated from both facet of the handguard.
Stribog SP10A3 Magazines
The journal launch splits the distinction between an AR-style button and an AK latch launch. It has a button on either side and a latch. The only lefty-unfriendly function is that the bolt launch is positioned on the left facet solely.
Along with M-Lok slots on the left and proper of the handguard, the Stribog has a bit of steady Picatinny rail alongside the sight aircraft for mounting backup iron sights and optics, whereas a shorter part hangs beneath for a weapon mild or a QD sling attachment.
The Stribog ships in a tough case with three 20-round translucent magazines.
Disassembly of the Grand Energy Stribog SP10A3 10mm
Subject stripping the Grand Energy Stribog is easy. The decrease has two captive retaining pins, like an AR decrease. Pushing them out to the proper facet frees the 2 halves to come back aside. The bolt, recoil spring, and barrel could be accessed by briskly flattening and out on the polymer inventory adapter. The barrel is fastened in place and requires a torque wrench for removing, however with the bolt eliminated, there’s loads of entry for cleansing.
On the Vary with the Grand Energy Stribog SP10A3
Because it comes out of its laborious case, the Stribog is a pistol-grip-only handgun and there’s no sighting system. I added my Viridian RFX 15 3 MOA Inexperienced Dot, which continues to experience on the Stribog with out difficulty. As I’m new to braceable pistols, I used to be thrown for a loop with the inventory adapter. It’s railed and I figured I must hunt down a brace that dovetails and screws in place.
Because it seems, that was not the case. There are a number of brace choices for the Stribog. SB Tactical and Strike Industries makes one. Rainier Arms has a minimalist brace with an integral sling level. I settled on a polymer folding brace from HB Industries. With the Stribog squared away, I headed to the vary with 400 rounds of 10mm to see what I may study.
Ergonomics
With a brace and this minimal optic, the Stribog SP10A3 weighs simply 6.6 lbs. absolutely loaded. Though the brace made shouldering a bit crowded for my six-and-a-half-foot body, I rapidly discovered my manner round it and concluded that the braced Stribog could be a fast deploying choice that doesn’t tire the arms and is about up excellent for somebody with a mean to construct.
As a southpaw, it was a deal with that the Stribog 10 is usually ambidextrous. The controls are straightforward to control on either side, even with my shorter thumbs. The journal launch drops empty magazines with authority, whether or not you select to press the journal button or flick the latch. The bolt launch is finest arrange for the right-hander’s capturing thumb, however it’s straightforward sufficient for a lefty who provides it a smack with the palm of the capturing hand. This labored out for me as I used to be reaching for the charging deal with with the identical hand when loading on a closed bolt.
From a capturing perspective, the SP10 is a pleasing balancing act. The 10mm Auto is a strong handgun cartridge and the light-weight and compact dimension of the SP10 lets you understand that. However the barrel rides on the lowest level of the higher receiver and the added weight over it retains the muzzle rise low sufficient that I may persistently hold it shouldered and see the inexperienced dot of my optic always. Recoil is a brisk push on the shoulder that you’ll really feel, however it’s not onerous with transient vary periods. I used to be, nonetheless, tempted to take a break after my first hundred rounds.
Taking pictures With the Stribog SP10A3
Braced pistols mix a few of the constructive options of devoted handguns and rifles however by no means utterly. The 10mm Auto isn’t a rifle spherical, however it’s straightforward to anticipate higher accuracy with a 3rd level of contact with a brace and an extended 8-inch barrel in comparison with a handgun. I zeroed the rifle at 25 yards and the lion’s share of my capturing was at that distance. I did go for teams from the bench at 50 yards and tried my hand at metal out to 100 yards.
I didn’t take a look at all kinds of ammunition by way of the Stribog SP10A3. Many of the 4 hundred rounds I went by way of consisted of Sellier & Bellot 180-grain FMJ goal ammunition. However I additionally had a field of Hornady Customized 155 grain XTPs and Buffalo Bore 220 grain laborious forged flat level ammunition.
Accuracy
At fifty yards, I may reliably get 5 rounds right into a 3-inch group utilizing the S&B load. The XTPs carried out equally however printed an inch and a half greater. The Buffalo Bore Outdoorsman load’s group opened as much as 3.5 inches however hit the identical level of intention because the S&B load. The accuracy could have been higher with a magnified optic, however the reflex sight suits properly for what is predicted out of a PCC and I discovered the accuracy to be greater than sufficient for private protection and even searching medium sport like hog or deer.
Offhand, it was straightforward to knock my 8-inch metal plates at 50 yards and I may reliably hit a 1/2 dimension metal silhouette at 100 yards so long as I switched to decaf. Transitioning from goal to focus on was a bit slower in comparison with a conventional 9mm PCC, because the SP10 needed to maneuver round extra, despite the fact that I by no means overpassed my optic window or my goal. However the 10mm is hitting these plates with extra authority and fewer drop. At 100 yards, my rounds struck simply three inches beneath my aiming level. That’s not a lot drop for a pistol spherical.
Energy
Handgun hunters, together with our personal Kat Ainsworth, belief the 10mm Auto as a searching cartridge–out of a handgun. It’s a highly effective flat capturing choice which you could pack in a holster. Placing the 10mm in a carbine helps within the accuracy division past typical pistol distances, particularly for common shooters like me. However does that longer barrel additionally assist increase the ten power-wise?
The reply is sure, marginally. I fired the SP10A3 for a number of five-round strings throughout my Caldwell chronograph from a distance of ten ft to shed some mild on how velocities would possibly enhance over a traditional handgun.
The Buffalo Bore load, marketed as harmful sport drugs, clocked in at a mean velocity of 1,388 ft per second over an marketed velocity of 1,200 ft per second. The Hornady Customized load, with its mild bullet, has an marketed velocity of 1,410 out of a 5-inch barreled handgun. It got here in at 1,603 ft per second. The S&B load has an marketed velocity of 1,150 ft per second. Out of the eight-inch Stribog, this spherical got here in a 1,244 ft per second.
A real 16-inch barreled carbine would possibly yield the very best outcomes however at the price of compactness. However even probably the most underloaded 10mm spherical is faring higher out of the Stribog, which could make the distinction relying on what you need to shoot at.
Reliability
The Stribog SP10 was an fascinating capturing expertise, however not as a consequence of an absence of reliability. It’s boring in that facet as I had no failures to feed, hearth, or eject. I initially had doubts about how a blowback-operated motion would possibly have the ability to deal with the 10mm spherical over typical lower-powered rounds like 9mm or .45. These doubts have been unfounded.

The 10mm Auto cartridge went to the proverbial dustbin of historical past within the early Nineteen Nineties not for lack of efficiency however for institutional and political causes. Though it’s not a magnum revolver spherical, the 10mm has its virtues that merely didn’t go away as a result of it misplaced reputation. The ten deserves its resurgence and there are actually extra 10mm pistols available on the market than there have been throughout its transient heyday.
