Best Glock Compensators: Top 3 Picks

Pistol compensators are some of the most popular Glock accessories purchased by pistol owners. Every pistol shooter wants to improve accuracy and speed. This is especially true of shooters who are active in competitive shooting. Two of the factors in pistol shooting that affect the speed of target re-acquisition are muzzle rise and felt recoil. A properly installed and designed compensator can help reduce or eliminate both of these problems.

Best Glock Compensator

A compensator works by redirecting a portion of the expanding gases through openings in the barrel or a device attached to the barrel threads to compensate for the natural muzzle flip and recoil that occurs. Various designs are incorporated to perform this function. Glock compensators can be integrated into the pistol barrel or threaded barrels may be added to your Glock pistol for mounting a compensator.

Like any aftermarket accessory, compensators come in different styles with different designs and at different levels of quality. My goal in this article is to look at what I consider to be the best Glock compensators on the market in various styles and designs.

What I Look for in a Glock Compensator

There are several factors that I consider essential in any pistol compensator. These represent the criteria that I used when considering the Glock compensators that went into making this list. You should remember that the best Glock compensator for you is the one that fits your needs and fulfills your expectations.


I always consider cost when evaluating products. I have learned over time that cost is not always a good predictor of quality or function. In my opinion, cost should be considered only as it relates to function, reliability, and quality. You may find that the best Glock compensator for your use is not necessarily the most expensive.

Ease of Use

No matter what kind of shooting you anticipate, the addition of a compensator should not materially affect your use of your pistol. If you routinely concealed carry your Glock, the compensator you choose should not inhibit your ability to carry your firearm concealed. Competitive shooters have different needs and should anticipate finding a compensator for their Glock that performs best during competition.


It may sound redundant, but you want your Glock compensator to perform to your expectations. You must also be realistic in those expectations. No compensator will eliminate all muzzle flip nor will they completely reduce recoil. However, realistic expectations can be met with the proper compensator selection.


If you choose a compensator that attaches to the end of the barrel of your Glock, there are weight considerations to be made. Adding anything to the forward end of your Glock pistol will change the balance of the firearm and the way it handles and shoots. This can be an issue with some heavier and bulkier compensators meant for threaded barrels.

My Choices for the Best Glock Compensators

The Glock compensators that I have chosen for this list are, in my opinion, the best Glock compensators on the market in the category to which they are assigned. In some cases, I may choose a runner-up when there is so little difference between the two compensators that either one is a good choice. I hope that the information in this list helps guide you in your selection of a Glock compensator.

Best Overall Glock Compensator for Threaded Barrels – Agency Arms 417 Compensator

  • Short overall length is an excellent choice for concealed carry applications
  • Works well without having to tweak recoil springs to accommodate different loads
  • High-quality machining
  • The manufacturer recommends using thread lock material during installation which can make removing the compensator more difficult in the future

My Thoughts on the Primary Machine Stealth Comp

Most Unique Glock Compensator – Tyrant Designs T-Comp Compensator

Competition in the firearms accessory business is a huge generator of innovative design. Tyrant Designs has taken that whole Glock compensator concept to new levels of out-of-the-box thinking with the Tyrant Designs T-Comp. This design is a fresh concept in compensator design and manufacturing.

Tyrant Designs compensators

Most compensators depend on one or more set screws to lock the compensator in place on the pistol. The overall look of the Tyrant T-Comp device is as unique as its mounting system. This compensator will definitely give your Glock a different look along with a host of great features.


You may forget about the features when you first look at the Tyrant Designs T-Comp muzzle device. However, you shouldn’t neglect the features that come standard with the T-Comp unit.

No Set Screws and No Thread Lock Material

Several other compensators omit the need for set screws, but very few omit the need for a thread locker to secure the compensator to the barrel threads. The Tyrant Designs T-Comp eliminates both with its unique mounting system. In effect, the two-piece design locks the body of the compensator to the slide.

Dual Expansion Chambers

The dual chambers of the T-Comp redirect expanding gases upward to reduce and offset muzzle rise. As the gas expands and cools leaving the compensator, it also reduces recoil. If you reduce muzzle rise and lessen sensed recoil.

Multiple Color Options

The Tyrant Designs T-Comp compensator comes in multiple color options. You can specify black/black, black/gold, black/nickel, or gold/black. The first color in each combination is the color of the outer portion of the compensator.

Reliability and Compatibility

The operation of the T-Comp with almost any ammo type is very good. Under most circumstances, no adjustments to the recoil spring are required for consistent operations. Unfortunately, the T-Comp is compatible with only Gen 3 through Gen 5 Glock models.

Tyrant Designs T-Comp

The Pros and Cons of the Tyrant Designs T-Comp Compensator

  • Installation is accomplished without set screws or thread locking materials
  • Operates with most factory ammo loads with no other tweaking or adjustments
  • Unique design and color options provide user customization
  • Lighter weight than most other compensators
  • Available for Gen3, Gen4, and Gen5 Glock Models

My Thoughts on the Tyrant Designs T-Comp Muzzle Device

First things first. This is a great-looking compensator. Added to a customized Glock pistol and you can build an eye-catching piece of equipment. I know. I am not supposed to be putting visual appeal over functionality. But, when functionality is of no question then you can afford to put visual appeal on the list. This is hands down a great compensator.

Micro Size

The Afterburner compensation system is only .47 inches long. This very small footprint reduces overall weight making less of an impact on balance. In addition, the shorter length keeps your pistol compatible with most holsters.

  • Requires using the Radian RAMJET barrel

My Thoughts on the Radian Afterburner Compensator System

If your Glock doesn’t already have a threaded barrel that is required by most other compensator systems, you must buy a barrel anyway. In that sense, purchasing the entire kit from Radian makes sense. The micro design is another huge plus and makes the Radian Afterburner kit the ultimate choice in my book.
