The Shield Arms S15 Gen 3 Combo brings genuine capacity relief to your Glock 43X or 48 with three 15-round magazines and a steel mag catch—a practical upgrade for shooters who want more rounds on tap without changing platforms. Unlike the factory plastic catch, Shield Arms' steel alternative is engineered to reliably feed and retain the taller S15 magazines, which hold five extra rounds compared to OEM single-stack mags. This combo gives you the flexibility to run higher capacity when you need it, swap back to standard mags for carry comfort, or keep backups ready at the range.
The Gen 3 magazines feature black nitride steel construction, the same durable finish that protects quality gun parts against corrosion and wear. Pairing them with Shield Arms' purpose-built steel mag catch isn't just a convenience—it's a reliability requirement. The company's testing showed that using their magazines with OEM plastic catches or incompatible aftermarket catches can introduce feeding issues. Swapping to their steel catch solves that problem and ensures the magazines perform as designed.
If you've already got first-generation aluminum mag catches on your Glock, note that you'll need to upgrade to a steel catch for the Gen 3 mags to run reliably. The combo kit takes the guesswork out of that transition by bundling everything in one box. Whether you're a competition shooter stacking capacity on the clock, a range regular who values spare mags, or a carry shooter who appreciates options, the S15 Gen 3 Combo is a straightforward way to expand what your compact 9mm can do.
| Magazine Capacity | 15 rounds per magazine |
| Magazine Material | Black nitride steel |
| Mag Catch Material | Steel, black nitride finish |
| Quantity in Combo | 3 magazines + 1 mag catch |
| Compatibility | Glock 43X, Glock 48 |
Yes. Shield Arms designed the Gen 3 S15 magazines to work with their steel mag catch. Using them with your factory plastic catch or other aftermarket catches can cause reliability problems. The combo kit includes the proper steel catch, so you're covered out of the box.
No. If you own a first-generation aluminum catch, you'll need to upgrade to a steel catch for the Gen 3 mags to function reliably. Shield Arms recommends replacing aluminum catches with one of their steel options.
The S15 Gen 3 magazines hold 15 rounds, compared to the standard 10-round capacity of Glock 43X and 48 factory magazines. They're constructed from black nitride steel and require the included steel mag catch for reliable operation.
Yes. Replacing the mag catch is a simple field-level task that requires no gunsmithing or special tools. If you're comfortable doing basic Glock maintenance, you can handle it.
