Shield Arms S15 +5 Magazine Extension – Glock 43X/48 (Gold)

The Shield Arms S15 +5 Magazine Extension increases magazine capacity by five rounds when used with Shield Arms S15 magazines in Glock 43X and 48 pistols. This extension transforms a 15-round S15 magazine into a 20-round magazine, providing a significant capacity increase while maintaining a manageable grip length. Designed specifically for concealed carry guns that benefit from extended capacity during range sessions or when maximum ammunition on board is required.

Machined from aluminum with a gold anodized finish, this extension adds approximately 1 inch to overall magazine length. Installation is straightforward—remove the magazine baseplate, insert the extension spring (included), and attach the extension. The unit locks securely to the magazine body and provides a positive grip surface. Compatible only with Shield Arms S15 magazines; will not work with factory Glock magazines.
