If you shoot a Glock in 10mm and you're tired of the 15-round factory cap, this is the easy fix. The SGM Tactical 30-round magazine doubles your capacity in a body that's built to actually hold up. The steel-reinforced polymer construction keeps the whole package lightweight without sacrificing rigidity, and the heat-treated continuous sheet metal lining protects the feed area where cheaper magazines tend to fail over time.
The internals are where this mag earns its keep. The anti-tilt polymer follower and stainless steel spring work together to keep rounds presenting consistently, even after a lot of use. Numbered witness holes down the side let you do a quick count without stripping the mag, and the redesigned +2 capacity floor plate is more than a cosmetic upgrade — it adds meaningful durability to the basepad and is part of how SGM gets to 30 rounds in the first place. The drop-free design means you're not fishing the mag out of the grip when you go for a reload.
Compatibility is broader than just the Glock 20. This magazine also fits the Glock 20SF, G29, G40, and any Glock-pattern PCC chambered in 10mm, including the Kriss Vector and B&T APC 10mm. That makes it a solid buy whether you're running a pistol at the range or feeding a carbine that takes Glock-style mags.
SGM Tactical backs this magazine with a consumer-direct lifetime repair or replacement warranty, which says something about how confident they are in the build quality. For range use, training, or competition where round count matters and reloads slow you down, this magazine is a straightforward, well-priced solution.
This magazine is designed for the Glock 20 and 20SF, and it also fits the Glock 29 and Glock 40 since all three share the same 10mm Glock magazine platform. Beyond pistols, it runs in Glock-pattern pistol caliber carbines chambered in 10mm, including the Kriss Vector and B&T APC 10mm. It is not a Glock OEM product, but it is engineered to Glock magazine specifications.
The standard factory Glock 20 magazine holds 15 rounds, so this SGM mag doubles your capacity in a single reload. The tradeoff is length — at just under 10 inches, this is a range and training magazine rather than something you'd carry for everyday use. For high-volume range sessions or competitive shooting where you want to minimize mag changes, the extra capacity is a real advantage.
The design uses an anti-tilt polymer follower and a stainless steel spring, which are the two biggest factors in keeping a magazine feeding consistently over time. The heat-treated metal feed lip lining reinforces the area most prone to wear and deformation in high-round-count use. SGM Tactical also tests their magazines with a variety of ammunition from multiple manufacturers to confirm feeding reliability across different load types.
Yes, the Kriss Vector Gen II accepts Glock-pattern magazines in 10mm, and this SGM Tactical 30-rounder is compatible with it. It also runs in the B&T APC 10mm and other Glock-pattern PCCs chambered in 10mm. It's actually a popular choice among Kriss Vector owners specifically because of the extended capacity.
SGM Tactical offers a consumer-direct lifetime repair or replacement warranty on this magazine. That covers defects and issues with the product itself. For warranty service, you would go through SGM Tactical directly rather than through a retailer.
Loading any high-capacity magazine to full capacity by hand takes some thumb effort, especially as you get close to round 25 and beyond with a big cartridge like 10mm. The anti-tilt follower and well-designed spring geometry help keep the loading process consistent. Using a quality magazine loader is an easy way to take the strain off your thumbs and speed up the process during a long range session.
