#SubGun

Beretta has a new variant of the PMXs, this time in tiger stripe. This new cosmetic variation has an MSRP of $1399. Let’s take a look at the PMXs more generally along with this new model.

The Brownells BRN family of upper receivers continues to grow with the addition of the BRN-9. This 9mm upper joins the 5.56, .300 BLK, and 7.62×39 options which are already available. Let’s take a closer look at what the BRN-9 brings to the table.

Safety Harbor Firearms continues to expand the lineup of Kompact Entry Stock (KES) with the addition of a Brugger & Thomet APC-9 model. Safety Harbor makes KES stocks and stabilizing braces for many popular PCC options. These include the CZ Scorpion, Grand Power Stribog, MP-5 and MP-5K, and Sig Sauer MPX. B&T has captured a large portion of the PCC market recently, so it makes sense that Safety Harbor added this model. Also, the APC-9K won the US Army Sub Compact Weapon contract in 2019.

We at TFB have been excited about the MDP-9 ever since Angstadt Arms set the hype train rolling with a promo video promising a new pistol calibre carbine. That gun, the MDP-9, was officially announced just before SHOT Show so it was great to get hands on with the gun and put a few rounds through it.

Just as Heckler & Koch reintroduced the original king of the roller-delayed blowback submachine guns – the MP5/SP5 last month Angstadt have rolled up with the next generation roller-delayed gun.

Charlotte, North Carolina-based Angstadt Arms have teased the unveiling of their new ‘subgun’, with a video featuring their previous pistol calibre carbine, the UDP-9. Angstadt have released a teaser trailer for the new MDP-9 but we don’t get a look at the new weapon, only hints.

Hot on the heels of some of the other successful Sub Compact Weapon programme contractors Charlotte, NC-based Angstadt Arms have unveiled their entry, the Angstadt SCW-9. Back in September  we reported that the US Army had selected 6 Sub Compact Weapon prototypes for testing. Contracts for test guns were placed with  Global Ordnance, Angstadt Arms, B&T USA,  Shield Arms, Sig Sauer and Trident Rifles.

Unlike many other countries, Russia always celebrates May 9. In fact, it is one of the biggest holidays of the year. On May 9, 1945, at 00.16 local time, Germans signed the Instrument of Surrender, which ended World War II in Europe.

Shooting subsonic ammunition in a properly suppressed host is a real eye opening event for the uninitiated. My first suggestion to anyone jumping into the silencer world is to pick a gun that can reliably run ammo specifically loaded to stay at around 1050 feet per second (or less). That could mean a .22LR bolt action rifle or a .300 Blackout short barreled AR15. But when it comes to pistol caliber hosts, submachine gun or pistol caliber carbines, especially the H&K roller delayed/locked varieties, are unmatched for quiet semiautomatic fun. The Dead Air team is launching a new subgun silencer into the market – the Wolf-9SD promises rugged modularity alongside expert level suppression.

The Sterling L2A3 was the iconic Cold War submachine gun of the British Army. Inexpensive to make, compact and rugged, it was a design that incorporated the experience from the Sten submachine gun, a weapon which though inexpensive really left a lot to be desired. In a recent video, Ian from Forgotten Weapons and working in concert with Armament Research Services (ARES), produced a video overview of some of the British developments in submachine guns (which they called “machine carbines”) just before, during, and after World War II. These designs helped pave the way for the Sterling, which saw service all the way through the Gulf War until its retirement in 1994.

Gone is the Caracal CC10 pistol caliber carbine from the UAE-owned company’s website, but in its place is a new, modern-looking submachine gun called the CMP9. This new weapon features integral 1913 rail mounting points on its aircraft-grade aluminum receiver, and a wraparound telescoping bolt system using the blowback principle. From Aftermath Gun Club:

Previously in TFB’s series on weapon operating mechanisms, we examined both the closed-bolt blowback system and the open-bolt API blowback system, two very close relatives that share a common feature: Closure of the breech through the inertia of the breechblock mass alone. What this means for small arms designers is that they must engineer a system where the breechblock is large enough to have sufficient mass, while having enough room to reciprocate the distance necessary for reliable ejection and feeding. In a standard submachine gun design using the API blowback system, for example, the breechblock is configured behind the breech end of the barrel, so that it can reciprocate. This is an easy design to engineer, and can be made simply and easily.

Previously on Operating Systems 101, we discussed the straight blowback method of firearms operation; today we’ll be talking about its close cousin, API blowback. “API” stands for advance primer ignition, which refers to the chief way that the mechanism differs from its pure cousin. We’ll get to that in a bit, but first we need to discuss the concepts of open bolt and closed bolt operation.

The first entry in our coverage of automatic weapon operating mechanisms will be the humble straight blowback method. Conceptually simple, it is one of the most common systems, being applied almost universally to .22 caliber rimfire autoloaders the world over, as well as being very commonly applied to budget centerfire handgun and rifle designs.

The Brazilian Polícia Militar do Estado do Rio de Janeiro (Rio de Janeiro Military State Police) have adopted the semi-auto only CTT40C carbines, made by Taurus. Below is an embedded video of the PMERJ’s introduction to the new short barreled carbines:
