Description
Warne is mostly known for optics mounts, but their magazine extensions are a genuinely solid product that flies a little under the radar. The MEG1932DE is machined from 6061-T6 aluminum billet and finished with a Type 2 hardcoat anodize in Flat Dark Earth, giving it both the durability and the look to match a serious build. The construction is noticeably more substantial than plastic base pads, and the FDE color is a natural fit for anyone running a tan frame, FDE slide, or coordinated gear.
The +3 capacity gain on a Glock 19 (or +2 on the Glock 23 in .40 S&W) might not sound like a lot, but extra rounds on a carry mag or competition mag make a real difference. The extension is shaped with finger grooves that give you something to grip when you need to strip the magazine in a hurry, and the overall profile promotes clean, positive insertion without snagging. It also meets the USPSA 141.25mm length requirement, so it works for production and carry optics divisions.
Installation is straightforward. You remove the factory base pad and retaining clip, drop the spring in with the follower oriented correctly, compress it below the magazine flange, slide the Warne extension on until the spring seats in the extension cavity, then tighten down the included Torx screw and washer. No tools beyond a Torx driver needed, and it uses your factory spring so there are no compatibility headaches.
Designed and made in the USA, this is one of those upgrades that just makes sense if you already own a Glock 19 or 23 and want a little more capacity with better grip ergonomics at the bottom of the mag.

Frequently Asked Questions
Will the Warne MEG1932DE fit all generations of the Glock 19 and 23?
The MEG1932DE is designed to fit Glock 19 and Glock 23 factory magazines. Since Glock 19 and 23 factory mags have remained consistent in their base dimensions across generations, this extension is broadly compatible. That said, it is intended for use with genuine Glock factory magazines, so results with aftermarket magazines may vary.
Do I need to buy a new spring to use this extension?
No, the Warne MEG1932DE is designed to work with your factory magazine spring. There is no need to purchase an extended or replacement spring, which keeps installation simple and eliminates any concern about spring compatibility.
Is this extension legal for use in USPSA competition?
Yes, the Warne Glock 19/23 magazine extension meets the USPSA 141.25mm overall length requirement, making it a viable option for Production and Carry Optics divisions. Always verify current rulebook requirements with your local match director if you have any doubt.
How difficult is it to install the MEG1932DE?
Installation is a straightforward DIY job. You remove the factory base pad and retaining clip, reinsert the spring correctly, compress it below the magazine flange, slide the extension on until the spring seats inside the cavity, and tighten the included Torx screw. All you need is a Torx driver, and it takes just a few minutes. A small drop of thread locker on the screw is worth considering if you plan to run it hard.
How does the FDE finish hold up with regular use?
The Type 2 hardcoat anodized finish is specifically chosen for abrasion and corrosion resistance, making it well suited for range use, carry, and competition. Hardcoat anodizing is one of the more durable finishes available on aluminum components, so it should handle normal handling and holster wear without issue.
Does the Warne MEG1932DE work on a Glock 23 in .40 S&W?
Yes, the MEG1932DE fits both Glock 19 (9mm) and Glock 23 (.40 S&W) factory magazines. The capacity increase differs by caliber, adding 3 rounds to a Glock 19 magazine and 2 rounds to a Glock 23 magazine due to the difference in cartridge size.
