Shield Arms S15 +5 Magazine Base Plate – Black

The Shield Arms S15 +5 Magazine Base Plate extends capacity for Shield Arms S15 magazines, adding five additional rounds to your Glock 43X or 48. This base plate transforms a standard 15-round S15 magazine into a 20-round configuration, providing meaningful capacity gains while maintaining reliability. Ideal for competitive shooters, range use, or anyone seeking maximum round count in their slim-frame Glock.

Machined from aluminum with a durable black anodized finish, this extension adds approximately 3/4 inch to overall magazine length. Installation requires disassembly of the existing magazine—follow Shield Arms installation instructions carefully and verify function before carry use. Compatible exclusively with Shield Arms S15 magazines; does not work with factory Glock magazines.
