Five top blowback action semi-autos

Five top blowback action semi-autos…

with the easiest to load magazines!

By Dennis Adler

Five different guns all with one thing in common, a self-contained CO2 BB magazine that is easy to load. Clockwise from bottom left, Umarex P.08 Parabellum, Umarex Beretta M92A1, Sig Sauer P226 X-Five, Tanfoglio Limited Custom and Swiss Arms SA 1911 TRS.

Blowback action semi autos burn through .177 caliber rounds almost as fast as a selective fire model on full auto. That’s a great part of their appeal; a realistic airgun experience that simulates the cartridge-firing model’s operation. A semi-auto is a fast gun to shoot and reload, which is why they are generally preferred over revolvers. But even with a self-contained CO2 BB magazine, like all five of the airguns featured here, the reloading experience can vary from slow to excruciatingly slow. Not with loading the magazine into the gun, that’s 100 percent accurate in every respect, but rather with loading the BBs into the magazine! Pressing anywhere from 8 to 15 rounds of 9mm, .40 S&W or .45ACP into a cartridge magazine is no picnic either, but each round goes on top of the other and gets pushed down into the magazine compressing the follower spring as you go. If CO2 BB magazines worked the same way, loading would be pretty straightforward. But that isn’t the way BBs load into a self-contained CO2 BB magazine. read more

Loading, Handling, and Accuracy

By Dennis Adler

The MP40 set the stage for decades of full-auto (and select fire) submachine guns built from the 1940s through the late 20th century, including the MP5 and Uzi. The Umarex MP40 is a nearly identical copy of the WWII subgun.

To wrap up the MP40 we need to review all of its operating features, which are very close to those of the original guns. First off, loading the magazine is accomplished by holding the follower down, inverting the magazine (cast alloy top pointing down) and loading the BBs into the port. This is a large, beveled port so feeding BBs is pretty easy, easier still with an Umarex speed loader. Load the magazine into the receiver with a firm push; set the safety to SAFE, pull the bolt to the rear and the gun is charged and ready to fire. read more

In the image of: MP40 comparison

By Dennis Adler

The MP40 has become one of the most recognized military arms in history, not so much for its actual use during WWII, but for its ever present roles in almost every WWII movie made in the past 70 years, including some of the best films of all time. The Umarex MP40 is a nearly perfect .177 caliber match for the legendary German submachine gun.

If there is success in numbers, then the MP40 was a success with production reaching an estimated 1.1 million by the end of WWII. But in the world of firearms, success is also measured by longevity, not production numbers alone, most mass produced military arms from WWII are no longer in use, many have simply been forgotten, while others have become collectible. The greatest example of longevity is the Colt Model 1911. In comparison to the Colt semi-auto pistol, the MP40 is only a minor success, but well maintained examples of the WWII German submachine guns are still being used to this day. More than 20 nations carried the MP40 for decades after WWII, some even into the early 21st century. So the MP40 has become one of the most recognized military arms in history. read more

Yes, this is the one you have been waiting for

a CO2 version of the most ubiquitous submachine gun in history

By Dennis Adler

The most commonly seen gun in almost every WWII movie about famous battles in Europe is the MP40. It was not only used by German soldiers but captured MP40s were used by the French Resistance and other partisans fighting against the Axis powers. Even American soldiers used them in covert operations. As a CO2 powered blowback action air gun, the MP40 stands among the most authentic historic reproductions. The Umarex MP40 is the gun on the bottom.

There is scarcely a WWII movie that takes place in Europe that does not have soldiers wielding an MP40 submachine gun; it has been used in every WWII and post war espionage thriller from the 1940s to the present day. We’ve seen the MP40 so often, in fact, that we almost don’t see it; it’s a part of the scene, as much as uniforms and dialogue. Both in film and in fact, the MP40, Walther P.38 and Luger P.08 are the very definition of WWII German arms; so they are SOP in any movie or TV prop house. But to say that the MP40 is the most famous submachine gun in history would be less than factual, there are many more famous, like the Thompson, and the Uzi, for example, but certainly none with more screen time, more time in the field of battle, nor more desirable as a blowback action CO2 model. Nearly 80 years after the MP40 was developed the guns are still being used in battle torn areas throughout the world, including the Middle East. Although vastly outdated, even by 1945 when the StG 44 was introduced, the MP40 has remained a solidly reliable (when handled properly) weapon using the most common cartridge in the world, the 9x19mm. The Umarex Legends version puts all of that into your hands in .177 caliber. read more
