Factors to Consider When Looking for the Best Glock Suppressors

Material

The type of material used to construct the suppressor will reflect directly on its performance and durability. Since a suppressor controls the pressure of expanding gasses that leads to the sound suppression.

Suppressors constructed from less effective metals may melt down or crack, especially under auto fire. As such, looking for a full auto rated suppressor may be the solution to this.

Caliber

Most suppressors are not interchangeable among different calibers. While you may still use large caliber suppressors on smaller caliber weapons, that might not be the best option as it would require different mounting mechanisms. As such, you should always choose suppressors that match with your Glock’s pistol caliber.

Mounting mechanism

Suppressors will come in either thread pitched or quick detach. For the suppressor to mount on your Glock’s muzzle, the threading must be compatible. If you wish to interchange your pistol suppressor among different pistols quicker, you should go for a quick detach suppressor.

Usability

The main functions of a suppressor is its sound and recoil reduction capabilities. A 9mm pistol will generate approximately 160 decibels while the safe limit of sound around your ears are only 85 decibels.

Hence, most shooters will add a suppressor to their Glocks in order to significantly reduce the noise and recoil generated.

Point of impact

The point of impact is the shift in the aiming point of your firearm after you mount the suppressor to its barrel. For this, it’s always a good idea to get the best suppressors that come with a minimal POI shift.
