RWB Glock 17 9mm Luger 33-Round Extended Magazine - Black

The RWB Glock 17 9mm Luger 33-round extended magazine is built for shooters who want serious capacity without sacrificing reliability. Whether you're running drills at the range, competing in action sports, or building a versatile defensive platform, this high-capacity mag gives you significantly more rounds on board than factory 17-round tubes. The polymer-metal lined construction balances durability with weight, and the design feeds 9mm Luger ammunition reliably through your Glock platform.

What makes this magazine stand out is its broad compatibility. Beyond the Glock 17, this 33-rounder also fits Glock 18, 19, 26, and 34 models—so if you run multiple guns in the same caliber, you can use the same magazines across your quiver. That flexibility simplifies logistics and means fewer SKUs to track during training or competition.

The black finish is straightforward and durable. The extended capacity does add length compared to standard magazines, so make sure your holster and carry system accommodate it before you field it. For range days, match training, or anyone who wants to minimize reload frequency during extended shooting sessions, this RWB mag delivers the round count without the complexity of competing systems.

Frequently Asked Questions

Will this 33-round magazine work in my Glock 19?

Yes. The RWB 33-rounder is compatible with Glock 17, 18, 19, 26, and 34 models. It will feed and function in your Glock 19, though the extended length will protrude beyond the magazine well.

What's the difference between this and a standard Glock magazine?

The primary difference is capacity. Standard factory Glock 17-round magazines hold 17 rounds; this RWB extended magazine holds 33 rounds of 9mm Luger. That doubled capacity means fewer reloads during extended range sessions or training.

Is this magazine compatible with all 9mm firearms?

No. This magazine is designed specifically for Glock-pattern mag wells. It will not work in other 9mm platforms like M&P, CZ, or other systems. Confirm your firearm is a Glock 17, 18, 19, 26, or 34 before purchasing.

Can I use this magazine for concealed carry?

While it is compatible with Glock 26, 17, 19, and 34 models, the 33-round capacity creates an extended magazine that protrudes significantly. Most standard concealed-carry setups and holsters are designed around shorter, standard-capacity magazines. Check your holster compatibility first.
