Running a Glock hard—whether on the flat range or during a long training block—means two things matter more than anything: consistency and capacity. Fumbling with constant reloads breaks focus and eats training time. Extended mags fix that, and a reliable five-pack keeps your kit squared away for drills, loaners, and spares without raiding your ammo budget.
The ETS-GROUP GLK-18-40 5 Pack delivers exactly that: five extended 40-round 9mm magazines built for double-stack Glocks, ready to keep you shooting instead of stuffing mags every three minutes. Shop this product
Why capacity matters for 9mm Glocks
In 9mm, time on the trigger is the currency of skill. Extended 40-round magazines let you increase string length, diagnose recoil control, and work transitions without breaking rhythm. That translates to better data on your shooting and more efficient reps. For defensive practice, longer strings mean you can work movement, target arrays, and malfunctions without turning every rep into a reload drill.
With 9mm’s balanced recoil and broad ammo availability, it remains the go-to caliber for most Glock shooters. Pairing that with 40-round mags gives you the bandwidth to train on what matters: sight tracking, cadence, and clean manipulations.
What you get with the five-pack
This pack is straightforward: five extended magazines, each holding 40 rounds of 9mm for double-stack Glock platforms. They’re affordable and built to be run. Ets Group and their Elite Tactical Systems line have made a name by delivering polymer magazines that just work—this bundle simply multiplies the utility. If your range bag has room for five, this is a smart way to load it out.
Fit and platform compatibility
The ETS-GROUP GLK-18-40 5 Pack fits the Glock 17, 18, 19, 19X, 26, 34, and 45, spanning Gen 1 through Gen 5. That broad compatibility is a major advantage for households, departments, or training partners running mixed models. If your pistol’s a standard double-stack 9mm Glock, you’re covered. It’s a single solution that bridges duty-size, compact, and subcompact frames—handy when you want the same mags to support different roles.
Modularity and maintenance
Magazines live a hard life: drops on concrete, dirt, and constant compression. These use base plates that are interchangeable with the rest of the ETS 9mm double-stack line, making spares simple and maintenance painless. Disassembly is easy thanks to a specially designed base plate—no wrestling with tabs or resorting to tools every time you need to clean grit out after a dusty range day. When a mag is easy to service, you’re more likely to keep it running at 100%.
Ergonomics for faster work
The floor plate is ergonomically shaped to make grabbing from pouches more secure. That matters when seconds count or when you’re reloading under fatigue. A consistent purchase helps lock in index points, reducing the chance of fumbles and keeping your reloads fast and repeatable.
Run time on the range
Forty rounds per mag changes how you train. It allows longer drills and meaningful pressure testing. Work rhythm on Bill Drills, then stretch to multiple targets, movement, and shoot-house style arrays without pausing every other string. If you’re instructing, a five-pack means you can keep a student on task while another loads, or you can preload the day’s evolution and stay focused on coaching instead of stuffing brass into polymer.
Because these mags are built for common 9mm Glocks across generations, they slot right into most training plans. Whether you’re running a full-size 17 or a compact 19, you’ll reap the same benefit: more time shooting, less time loading.
Durability and reliability
Extended magazines demand reliable geometry and consistent spring tension. The ETS design has been refined with those priorities in mind. Between the robust body and serviceable base plate, you can manage the two big killers of magazine performance—debris and wear—without hassle. Pair that with a Lifetime Warranty, and it’s clear these are meant to be used, not babied. If a mag is down, you service it; if it’s out, you replace it. Either way, you keep training.

Price point and value
At a listed price of $41.39, this bundle hits a smart balance between cost and utility. Factor in the time savings and training efficiency from 40-round strings, and the math leans in your favor. Buying as a five-pack also gives you redundancy—the golden rule for magazines. Keep two for primary use, two as spares, and one reserved for diagnostics or loaner duty during classes. That distribution keeps your system resilient and your time on target uninterrupted.
Setup tips for best results
Mark, rotate, and record
Number each mag with paint pen, track use, and rotate them. If issues pop up, you can identify the culprit instantly and keep shooting with the rest.
Load discipline
Use consistent ammo when testing reliability. Run your defensive or duty load for proofing, then train with your preferred range round. Keep logs—round count, malfunctions, conditions. With extended magazines, consistency gives you clean data and confidence.
Clean smart, not constantly
The easy-disassembly base plate means you can service these after dust, mud, or heavy drop sessions without chewing up time. You don’t need to clean after every outing, but don’t hesitate after dirty days.
Compatibility notes and considerations
These are 9mm double-stack Glock magazines compatible with Glock 17, 18, 19, 19X, 26, 34, and 45 across Gen 1–Gen 5. If you run mag pouches sized for standard 17-rounders, check retention and clearance with the extended floor plate and added length; most quality pouches adjust easily. As always, magazine capacity laws vary by location—verify local regulations before ordering or traveling with 40-round magazines.
Who this five-pack is for
If you’re a Glock shooter intent on improving speed and recoil control, this pack is a strong move. Instructors and agencies will appreciate the simplicity of one pack covering mixed Glock models from Gen 1 through Gen 5. For casual range days, it removes the single most annoying bottleneck—constant reloads—so you can focus on fundamentals and have more fun doing it.
Final thoughts
Extended 9mm Glock magazines should do three things well: feed reliably, survive hard use, and be easy to service. The ETS-GROUP GLK-18-40 5 Pack checks those boxes while covering nearly every double-stack 9mm Glock from Gen 1 to Gen 5. Add an ergonomic floor plate, interchangeable base plates across the ETS 9mm line, simple disassembly, and a Lifetime Warranty, and you’ve got a dependable training force multiplier at a price that makes sense. Stack them, mark them, and get to work.
