FAB Defense ULTIMAG Glock 17 18 Round Polymer Magazine Review

First Impressions of FAB Defense ULTIMAG Glock 17 18 Round Polymer Magazine

The FAB Defense ULTIMAG Glock 17 18 Round Polymer Magazine promises enhanced reliability and ergonomics for Glock 17 owners, all at a very attractive price point. As someone constantly seeking to optimize my gear, especially magazines, I was eager to see if this offering from FAB Defense lived up to the hype. My primary motivation was to find a cost-effective, reliable alternative to factory Glock magazines for both range use and potential backup in tactical situations.

My initial experience was a mixed bag. The magazine felt surprisingly lightweight, which initially raised concerns about durability, but also sparked curiosity regarding its polymer composition. Compared to Magpul’s Glock magazines, the ULTIMAG felt less robust, but the aggressive texturing on the magazine body promised a secure grip. Would this ULTIMAG solve my quest for affordable reliability, or would it be another range toy?

Unboxing revealed the magazine in simple packaging. My first impression was that the polymer felt slightly less dense than other polymer magazines I’ve handled. I was initially surprised by the lack of any metal reinforcement in the body, relying solely on the polymer and spring.

I decided to put the FAB Defense ULTIMAG through its paces, hoping it would prove its worth despite my initial hesitations.

Real-World Testing: Putting FAB Defense ULTIMAG Glock 17 18 Round Polymer Magazine to the Test

First Use Experience

My first outing with the FAB Defense ULTIMAG Glock 17 18 Round Polymer Magazine was at my local outdoor range. The day was mildly dusty with temperatures hovering around 75 degrees Fahrenheit. I loaded the magazine with 18 rounds of standard 115-grain 9mm FMJ ammunition.

Insertion into my Glock 17 was smooth, and the magazine locked in place with a positive click. During the first few magazines, I experienced two failures to feed where the slide failed to fully chamber the round. I was a little disappointed.

Extended Use & Reliability

Over the next few weeks, I continued to test the ULTIMAG, putting roughly 500 rounds through it in various drills and practice sessions. After the initial break-in period, the magazine’s reliability noticeably improved. I encountered no further failures to feed after the first 100 rounds.

The polymer showed minimal signs of wear, despite being dropped onto concrete multiple times. Cleaning the magazine was straightforward; the tool-less disassembly made it easy to remove the floor plate and spring. I can confirm that FAB Defense’s claim about tool-less disassembly is accurate. This ease of maintenance is a significant plus for regular use.

While not as robust as steel magazines, the ULTIMAG proved itself to be a viable option for range use and a reasonable choice as a backup magazine.
