Glock Factory Magazine Gen 4 for Glock 19 - 9mm Luger, Polymer Black

A Glock Factory Magazine Gen 4 for Glock 19 in 9mm Luger is the surest way to keep your pistol running exactly as the manufacturer intended. Built to Glock's specifications in Austria, this genuine factory magazine is the standard against which aftermarket options are measured—not because of marketing, but because it's engineered and tested by the people who designed your gun. Whether you're stocking spares for the range, building a carry rotation, or setting up a duty rig, OEM reliability matters when lives and competitions are on the line.

The polymer construction keeps weight minimal while maintaining the durability Glock is known for. A round count indicator molded into the rear face of the magazine body lets you track your ammo at a glance—no guessing how many rounds you've run or how much capacity remains. The standard Glock factory baseplate is durable and field-proven, with no surprises or compatibility quirks to worry about.

If you carry, compete, or train with a Glock 19, genuine factory magazines should be your baseline. They're not fancy, they're not the cheapest option, and they're not trying to be. They're simply what works, every single time, because Glock designed them to work with your gun.

Frequently Asked Questions

Will this magazine work with other Glock models?

This magazine is specifically manufactured for the Glock 19 Gen 4. While some Glock magazines are cross-compatible across models, we recommend verifying compatibility before purchase if you own other Glock pistols.

What does the round count indicator do?

The round count indicator is a series of witness holes on the rear face of the magazine body that let you see approximately how many rounds are loaded without removing the magazine from your gun.

Is this a genuine Glock factory magazine?

Yes. This magazine is manufactured to Glock's specifications in Austria by Glock, Inc. It includes the standard factory baseplate and comes with all the durability and reliability you expect from genuine OEM parts.

How many of these should I have?

That depends on your use case. Competitive shooters and active trainees typically run three to five magazines per firearm. Carry and home defense users often keep at least two or three on hand. We recommend starting with extras and building from there based on how often you shoot.
