Glock 19 Compensator (5 Best)

Whether you’re building a brand new gun from scratch using a 3D printed or Polymer 80 frame, or you already have a Glock 19 and want to spice it up a little bit, a compensator is one accessory you will want to include.

What is a Compensator (for Glocks)?

A compensator is an accessory added to the barrel of a gun that reduces recoil and helps improve accuracy by redirecting expelled gasses upward. The upward expelled gas compensates for the recoil and minimizes it, thus the name compensator.

The result is less felt recoil each time you pull the trigger. This allows the firer to get back on target quicker and more accurately, resulting in faster follow-up shots and tighter shot groups.

How Does a Compensator Work?

Think Newton’s Third Law of Motion. Need a refresher on your physics? Newton’s Third Law of Motion states that for every action, there is an equal and opposite reaction.

how g19 compensator works

In a compensator, the gas created by the combustion of the gunpowder is forced out of vents on the top of the compensator placed at the end of the barrel. 

The force that the gas generates leaving the vents upward creates an equal and opposite force downward. That downward force that is created helps to compensate or minimize, the recoil felt when the slide slams to the rear during firing.
