What’s the Verdict on the SGM Tactical 50-Round Drum?
After handling and testing this unit, I can tell you it’s a functional, budget-conscious option for shooters who want high capacity without a premium price tag. It’s not a KCI or a Magpul D-50 in terms of fit and finish, but for the money, it feeds reliably and gives you that 50-round capability. Think of it as a tool for the range or a backup for your kit, not a duty-grade piece of gear. For $59.99, shipped same-day from Boise, it delivers on its core promise.
What Are the Key Features of This Drum Magazine?
This isn’t just a big plastic box. SGM Tactical built this drum with specific engineering choices that matter on the firing line.
- Windowed Back Plate: The clear polymer window lets you visually confirm your round count at a glance. You don’t have to guess or try to feel how many are left.
- Glock-Compatible Feed Lips: This is critical. The feed geometry is designed to match OEM Glock specs, which promotes reliable feeding and reduces the chance of a misfeed under rapid fire.
- Polymer Construction: The entire body is made from impact-resistant polymer. This keeps the weight down compared to all-metal drums, which is noticeable when it’s fully loaded.
- 50-Round Capacity: The obvious main feature. It uses a rotary drum mechanism to stack and feed the 9mm rounds efficiently.
- Standard Glock Magazine Release: It locks into your Glock’s magwell just like a standard magazine. No special modifications or adapters are required.

The SGM sits in a sweet spot. It’s not the cheapest no-name import you’ll find on a sketchy site, and it’s not the premium-priced Magpul. You’re paying for a known brand with better QC than the generics, but you’re not paying for the absolute top-tier engineering. For most shooters who want a drum for fun, this is the sensible middle ground.
What Are the Pros and Cons?
Pros:
- ✅ Cost-Effective Capacity: Fifty rounds for under sixty dollars is a solid value proposition.
- ✅ Reliable Feeding: In our tests, it fed 9mm range ammo without hiccups. The Glock-style feed lips work.
- ✅ Functional Round Count Window: The window is genuinely useful, not a gimmick.
- ✅ Lightweight for a Drum: The polymer construction makes it manageable, even when full.
- ✅ Ready to Ship: We have these in stock in Boise and can get it out the door today.
Cons:
- ❌ Not for Duty Use: This is a range or training magazine. If your life depends on it, stick with OEM or premium brands. See our Magazines category for other options.
- ❌ Loading Can Be Stiff: The spring tension is strong, especially when new. A magazine loader is highly recommended.
- ❌ Adds Bulk: This is true of any drum. It changes the handling and holstering of your pistol significantly.
Who Should Buy the SGM Tactical 50-Round Drum?
Buy it if: You’re a recreational shooter who enjoys high-capacity fun at the range. You’re a competitive shooter in a division that allows drums and you want a budget-friendly option to test the waters. You’re building a “fun gun” or a range kit and want the extended capacity for drills without constant reloading. You value the round-count window for keeping track during strings of fire.
Skip it if: You need a magazine for defensive or duty carry. You demand the absolute highest level of fit, finish, and durability regardless of cost. You’re unwilling to properly break in the spring and use a loading tool. You primarily shoot from a concealed holster—this magazine is not practical for that. For more compact or carry-oriented options, browse our standard capacity magazines.
Frequently Asked Questions
Will this drum magazine fit my Glock 19?
Yes. This SGM Tactical drum is designed for double-stack 9mm Glock pistols, which includes the Glock 19, 17, 26, 34, and other compatible models. It uses the same magazine catch interface as your standard magazines.
Is it difficult to load all 50 rounds?
The spring is robust, which is good for reliability but makes loading the last 10-15 rounds by hand a chore. I strongly recommend using a magazine loading tool, like an Uplula, to make the process easy and save your thumbs.
How reliable is this compared to a standard Glock magazine?
In our function testing with various 9mm FMJ ammunition, it has been reliable. It may not have the decades of proven track record of an OEM Glock mag, but for its intended range use, it performs well. Always test any new magazine with your specific firearm and ammunition.
Does the round count window work well?
Yes. The window is clear and the numbered follower is easy to see. It’s a simple but effective feature that lets you know exactly how many rounds you have left without having to unload the magazine.
Can I use this for competition shooting?
It depends on the specific competition rules. Some practical shooting or “fun match” divisions allow high-capacity drums. Always check your match rules beforehand. The magazine’s capacity can be an advantage in certain stages.
Where can I buy a Glock drum magazine online?
You can purchase the SGM Tactical 50-Round Drum Magazine right here at Glockswitchstore (glockswitchstore.com). We ship same-day from our warehouse in Boise, Idaho.
What’s the best way to store a loaded drum magazine?
Store it in a cool, dry place. It’s generally fine to keep it loaded, though periodically cycling the ammunition and function-checking the magazine is a good practice. The polymer construction is not affected by long-term spring tension in the same way some metal magazines might be.
