Suppressor Pistons: A Key Component of Handgun Suppressors

In almost every situation where you’ll be running a pistol and suppressor combination, you’re going to need a suppressor piston. This is unique to pistol caliber suppressors because of the way (most) semi-automatic pistols operate.

We’ll take a look at what pistons are, how they work, and more so that you know exactly what you’ll need for a successful trip to the range with your pistol and suppressor.

What is a Suppressor Piston?

A suppressor piston is a part of your suppressor on the end that attaches to the barrel of your host gun. It gives the gun’s mechanical operation a little extra help when dealing with the added weight of the suppressor and the corresponding change in the overall dynamics of the gun.

How Suppressor Pistons Work

Pistols that have tilting or sliding barrels rely on the recoil of the gun to properly cycle the action. The barrel must move to the rear slightly to unlock the action, which isn’t a big deal when the gun is being fired under normal circumstances.

With the added weight of a suppressor, it can slow down the cycling operation of your gun. Now, instead of just having to deal with the weight of the barrel and slide, your gun has to deal with the suppressor, too. Many guns are not designed to handle the extra weight, and so the action won’t cycle properly. This can result in it failing to eject a spent casing or failing to properly feed the next live round.

A piston helps your host gun offset the added weight of the suppressor. It actually drives the suppressor forward just a small bit while the barrel moves to the rear to unlock the action. This small bit of movement counteracts the suppressor’s weight and allows the gun to cycle properly.

Suppressor Pistons and Recoil Boosters

A suppressor piston is part of the recoil booster unit as a whole, which is made up of the piston and a spring. The spring fits over the piston. The combination of the piston and the spring make up the recoil booster.

The recoil booster does exactly what its name says it does. It briefly boosts the pressure at the muzzle so that the barrel can properly unlock and cycle your gun when equipped with a suppressor.
