FAQ 🤔

Does a Glock need a compensator?
📢 No, a Glock does not need a compensator; ⚠️ however, many people find that a compensator helps tame the recoil of the weapon.

🔔 Additionally, a compensator can help you stay on target for follow-up shots.

Do I need a threaded barrel for a compensator?
✅ The simple answer is yes, you do need to use a threaded barrel to install a compensator on your Glock 21. ➔ Compensators are typically installed onto the end of the barrel and require specific threading to be securely attached.

⭕️ Make sure that you select a threaded barrel compatible with your chosen compensator before purchasing either piece.

Are compensators worth it?
  • ✅ Compensators can be an effective way to reduce the recoil of your Glock 21, which can make it easier to keep the gun on target after each shot. Compensators also help reduce muzzle rise and increase accuracy, so they can provide a practical advantage to some shooters.
  • ❌ However, compensators come at a cost in terms of weight and might not work for everyone.

⚠️ When deciding whether or not you should purchase a compensator, you must weigh the pros and cons carefully.

What does a compensator do?
📌 A compensator (also known as a muzzle brake) is a device attached to the barrel of a firearm that redirects propellant gases to counteract the recoil force of the firearm. ⟹ In most cases, this means that the compensator will reduce or eliminate muzzle movement during firing.

  • 👍 This can be particularly helpful for firearms that are prone to recoil, such as pistols and rifles chambered in powerful calibers.

📌 Compensators also have the added benefit of reducing noise and flash from the firearm.

Do compensators reduce velocity?
👁‍🗨 Compensators reduce felt recoil and muzzle flip, however, they also have a slightly lessening effect on velocity:

  • ➔ they generally cause the bullet to exit the barrel at a slightly lower speed than it would without one being installed.

👁‍🗨 They are designed to reduce back pressure to compensate for muzzle rise (hence the name “compensator”) by venting gases away from the shooter upon firing.

Conclusion ⏰

If you are in the market for Glock 21 compensators, the information above must be helpful to you. In this article, we have provided an overview of the best compensators on the market, as well as recommendations on what to look out for when buying.

Before I fit my Agency Comp, should I remove the rubber spacer from the neck of my barrel?

Shannon Smith

Reply to  Immuseduentedo

The answer to this question depends on the type of compensator you are installing. ➔ Some compensators come with rubber spacers already attached, while others require that you remove them before making any changes.
🔸 If your compensator requires rubber spacers, it is recommended that you remove them before making any adjustments or changes. This will ensure a clean installation and prevent damage to both your pistol and the compensator itself.
🔹 If a rubber spacer is not included with your Compensator For Glock 21, then there is no need to take one off before installation.

I have PMM on my G19.5 and ARC Division on my G19.4. Installing the PMM was a major hassle – however, its sister product within the ARC Division proved to be far more user-friendly and is just as efficient (if not more).

My brother, a passionate gun collector, sent me an exceptional present for Christmas this year: a threaded barrel and compensator designed specifically for my Glock 21. During today’s shooting session I was impressed by the outstanding performance these components provided–not only did it reduce muzzle climb considerably but also decreased felt recoil significantly! Even with its added length, this combination is absolutely worth it.

Unfortunately, I’m unable to inform you of the compensator’s brand since my colleague removed all the packaging when he had to send it for work purposes. He doesn’t even recall what kind it was! All that remains is a logo on the compensator itself – same goes for the barrel too. It’s quite comical if you think about it.

From my experience, really great compensator out there is probably the Chevrolet Corvette followed very closely by the Ford Raptor. Both options can be beneficial depending on what type of animal you are searching for.

How do you, men, feel about the PMM barrel and compensator? Are they of poor quality, meaning that one needs to replace any springs or anticipate frequent failures?

I’ve got one on my model 45 and have shot numerous types of ammunition through it; unfortunately, some Winchester ammo caused trouble, though I’m convinced this was due to the specific type of ammunition rather than my USP.

Many people have the notion that a higher price tag will yield better quality. ⭕️ However, when it comes to compensator for Glock 21, this is not always the case.
✔️ Sure, some premium compensators are made with superior materials that provide a more consistent shooting experience, but there’s no guarantee that all expensive models will be top-notch.
✅ On the other hand, you could find some good inexpensive Compensator For Glock 21 from reputable brands like Strike Industries and Odin Works. As such, try to go beyond the cost of the Compensator For Glock 21 and read reviews instead before finalizing your purchase decision.

I recently acquired an EFK Fire Dragon barrel and compensator for my Gen4 Glock 21 (.45) but am now facing issues with light recoil. Not only is the slide failing to eject the casing fully, it’s also not locking back after all rounds have been fired from the magazine. Has anyone here any helpful ideas or solutions?

Increase the shooting power. Whenever I shoot my Glock 21 with Lone Wolf compensator, I have to use heavier loads for it to function properly – but when this is done, it works like a dream!
