Have you ever wondered how a 9mm carbine works?

One of these is the direct blowback system of operation used in pistol caliber carbines (PCC).

So, lets dive into exactly how a direct blowback firearm functions.

On the outside, all SAINT rifles appear similar. But on the inside, the Victor 9mm Carbine has a significantly different operating system. The author helps us understand how this 9mm carbine works.

How Does a PCC Work?

As you might imagine, the mass of the slide or bolt is critical to ensure proper operation.

Blowback operation is a relatively simple system that is considered to be a very reliable action.

A rifle like the SAINT 9mm Victor Carbine uses a direct-blowback design to operate the gun. There are no pistons or gas tubes to worry about.

It requires fewer moving parts than other firearm actions.

Springfield Armory, for example, uses this in its SAINT Victor 9mm Carbine.

The simplicity of the system frequently is demonstrated through the long life and low maintenance of the system.

Since there are fewer parts in a direct blowback system, there are fewer parts that can break.

Additionally, the parts that do exist tend to be bulkier and stronger.

At first glance, these two things appear to be incompatible.

A blowback system feeds from magazines like any other semi-auto rifle. The SAINT Victor 9mm Carbine uses the extremely reliable Colt-pattern32-round magazine.

With a high-quality firearm like the SAINT Victor 9mm Carbine, all factory ammunition should function fine.

The need for reliability is critical for self-defense.

But its critically important for competition as well.

Prospective competition shooters owe it to themselves to examine all of their options.

A quality direct blowback pistol caliber carbine should undoubtedly be in the running.
