Magazines are often the weakest link in any firearm system. Extended mags? Even more so. So when I saw a 34-round Glock-pattern mag selling for $5.99, I assumed it would be range toy quality at best—something you buy in bulk and treat like disposable brass.
But I was wrong.
The Rattlesnake Tactical 34-round 9mm magazine doesn’t act like a cheap mag. It locks up tightly, feeds reliably, and withstands the kind of testing that usually reveals cracks—both literally and figuratively.
Field-Tested with the Maxim Defense MD9
For testing, I ran two RTAC mags through my Maxim Defense MD9. Both mags locked in solid, dropped free when empty, and fed flawlessly using Blazer 115gr 9mm, HOP Munitions 9mm poly, and HOP Munitions 147gr 9mm JHP (my preferred defense load).
I ran each mag fully loaded multiple times—both racking the first round and using the slide release—and they cycled through every round without a single malfunction.
There was no noticeable flex when seating a full mag on a closed bolt, and the textured exterior made for easy handling during reloads. I didn’t baby these either—dropped them in the dirt, on concrete, and left them loaded for days. They kept running.
Not Just Another Clone
The RTAC mag was designed in collaboration with Ammunition Depot and isn’t some rebranded import.
It’s American-made, backed by a lifetime guarantee, and built using a high-tensile, non-memory spring paired with impact-resistant polymer. You feel it when you handle it. There’s no rattling and no weird molding seams.
It’s compatible with Glock double-stack 9mm models, such as the G17, G19, G34, G45, G47, and most Glock-magazine PCCs—Sub2000, Ruger PC Carbine (with Glock magazine well), and AR-9 builds. No-go for Glock 43/43X/48 or Ruger PC Charger, but that’s expected.
Third-Party Testing Results
This isn’t just me singing praises after a few range trips. Third-party testing put the RTAC 34-round mag head-to-head against two top-selling extended mags. The test protocol:
- 510-round live fire per mag
- Three Glock models: Gen5 G17, Gen4 G19, G47
- Blazer 115gr factory ammo
- Hand cycling, static drops (corners, feed lips, sides)
All mags failed the extreme feed lip drop test—no surprise there—but RTAC held its own in side and corner impacts. More impressively, it outperformed both competitors in long-term reliability.
Bottom Line
At this price point, I expected range-grade gear. What I got instead were two high-capacity mags that ran without issue in a demanding platform and held up under field abuse. If you’re looking to stock up on extended mags for your Glock or PCC, this is an easy buy.
At $5.99, it’s a no-brainer. Even at the full MSRP of $19.99, the RTAC 34-round mag punches above its weight.
Although they offer “duty performance” as the title suggests, I would not personally run them as my primary duty mags. They are great for range practice, training courses, and competition shooting.
Final Verdict: 4.5/5 pews. You don’t have to spend $30+ to get a reliable extended mag. Just make sure you get them while they’re still available at this price.
