The Shield Arms Gen 3 S15 is a 15-round magazine purpose-built for the Glock 43X and Glock 48, giving you 50% more ammunition capacity without changing the footprint of your carry gun. If you've wanted to boost your mag count on a slim 9mm without sacrificing the sleek profile that makes these pistols so packable, the S15 solves that problem—it's the same length as Glock's OEM 10-round magazine but stacks five extra rounds using patented geometry that staggers the rounds more efficiently in the mag well.
Shield Arms engineered this with the reliability Glock users expect: nickel steel construction with a black electroless nickel finish that delivers both corrosion resistance and lubricity. The Gen 3 iteration reflects a shift to US-based manufacturing, new steel with improved thickness and toughness, and refined heat treat processes designed to eliminate tolerance stacking from frame variations. The result is a magazine that feeds reliably, handles rough use, and resists rust in the field or on the range.
The S15 ships with an impact-resistant base pad that's easy to swap or remove, and the raised ribs on the back ensure consistent seating in the mag well across different Glock frame tolerances. Whether you're a concealed-carry shooter who wants spare ammunition on tap or someone who simply prefers to reload less often, this American-made mag bridges the gap between slim-profile carry and practical capacity.
| Capacity | 15 rounds |
| Caliber | 9mm |
| Fits | Glock 43X, Glock 48 |
| Magazine Length | Same as OEM Glock 43X/48 10-round magazine |
| Material | Nickel steel |

| Generation | Gen 3 |
Yes. The S15 is the same overall length as the OEM 10-round magazine, so it seats flush in the mag well and doesn't extend the profile of your pistol.
The S15 is built on the same reliability platform as Glock magazines. Shield Arms uses nickel steel with a modern QPQ heat treat process and black electroless nickel finish to ensure durability and corrosion resistance in field and carry conditions.
Gen 3 features US-based manufacturing, improved steel with refined heat treat, new raised ribs to match OEM mag-well positioning and eliminate tolerance stacking, and a durable black electroless nickel finish.
Yes, the impact-resistant base pad is designed for easy removal or swapping if needed.
