Tyrant Designs Glock Magazine Extension

Tyrant Designs Glock Magazine Extension

Tyrant Designs first came to my attention with their T-Comp series of compensators. Not being someone who carries with a threaded barrel, my attention was never held. Fast forward two years and I stumble across their magazine extensions. After seeing their unique locking mechanism, I ordered one for myself.

Mounting the Tyrant Designs Glock Magazine Extension

Tyrant Designs uses one of the most user friendly mounting methods I've found for their extensions. Disassemble your OEM Glock magazine before you begin. Next, transfer the follower onto Tyrant's enhanced power spring, and insert into the magazine body. From here, compress the spring, and slide the Tyrant extension on, from front to rear. Once fully seated, a spring loaded plunger pops up, preventing the magazine from sliding off the extension. All of this can be done without tools.

To remove the extension, simply depress the plunger and separate the magazine from the attachment. Interestingly, the plunger spring is light enough to be depressed using my thumbnail.

Dimensions

Machined from aluminum, Tyrant Designs extensions come in at a respectable 4.0 ounces. Shaping is unique, with a concave bottom, relieved sides, and a couple serrations on the rear. Edges are beveled, and the overall size is trim compared to offerings from Dawson Precision or even Shield Arms. Tyrant offers six satin finishes, with Gold being my choice here. Capacity is as advertised, adding five rounds, for a total of 22 in a G17 magazine. Staying under the 140mm mark makes these suitable for USPSA use.

Overall the texturing and shaping is solid. Users should have no issues retrieving their magazines from pouches or pockets, even in adverse conditions. Those using flared magwells are safe, as the smaller footprint easily fits in even the smallest models.

Function

Before being trusted on my belt all magazine extensions endure a drop test. Parameters are simple. Each magazine is fully loaded, then dropped five times onto concrete from shoulder height. Mags are dropped straight down onto the extension as though falling from a firing pistol. Wanting to take advantage of nice weather, I opted to conduct the drop test on my back patio. This was a mistake. Upon hitting concrete, the Tyrant extension popped of the magazine, with the extended spring disappearing into Oblivion. After recovering the other pieces, I contacted Tyrant Designs, who sent me a replacement spring. Further drops were performed in my garage for spring retention.

The second drop was more of the same, failure of the retention plunger. For the third drop, I removed five rounds from the magazine. Theoretically, the reduced weight and tension would improve results. No luck. The fourth and fifth drops were done without ammunition loaded. I wanted to see if the magazine would stay together in perfect conditions. Twice more was the result the same. The extension removed itself from the magazine, though less violently, when empty.

Damage to the extension itself is minor. Some slight dings along the edges from impacting the ground. There are a few scrapes internally from the spring pressing against the body under pressure. Otherwise things held up nicely.

Due to these consecutive failures, I did not proceed to live fire testing.

Final Thoughts on the Tyrant Designs +5 Glock Magazine Extension

The Tyrant Designs Glock magazine extension is unfit for duty, conceal carry, competition, or training use. If you want to run a stendo, look elsewhere. A few quality options include Arredondo, Dawson Precision, or Shield Arms.

MSRP on the Tyrant Designs Glock magazine extension is $39.95. I got mine on sale from Tyrant for $35.96.
