Shield Arms S15 Gen2 PowerCron 9mm Magazine with +5 Extension – 20-Round, Black

Maximize your Glock 43X and 48 capacity with the Shield Arms S15 Gen2 PowerCron 9mm Magazine with Pre-Installed +5 Extension. This factory-assembled combination delivers a 20-round capacity in a slim, single-stack form factor — offering serious firepower without sacrificing concealability.

The S15 Gen2 PowerCron base magazine is engineered for precision fit and reliable feeding, and it arrives with a Shield Arms anodized aluminum +5 magazine extension already installed. The extension is machined from billet 6061 aluminum and features a Type 2 anodize finish for lasting durability. Index cuts on the extension body improve grip during mag changes, and the unique easy-access floor plate design lets you quickly service or clean the magazine body without removing the extension — a thoughtful feature that saves time at the range and in the field. A 12-coil high-power spring is included to ensure consistent, positive feeding through all 20 rounds.

**Important — Mag Catch Requirement:** The S15 Gen2 magazine requires a Shield Arms steel magazine catch. The factory OEM plastic mag catch must be replaced with either the Shield Arms Standard Steel Mag Catch or Premium Steel Mag Catch to ensure proper function and reliability. First-generation aluminum mag catches must also be upgraded. Using a third-party or incompatible mag catch may result in feeding and retention issues.
