Shield Arms, Extended Magazine, Glock 19 OEM, 9MM, 20 Rounds, Fits Glock 19, Aluminum Material, Anodized Finish, Black - SKU: G19-ME-5INS-BLK - UPC: 810159260992
Product Description
The Shield Arms G19-ME-5INS-BLK is a pre-assembled, factory-built 20-round extended 9mm magazine designed for double-stack Glock 19 handguns. Combining a factory original OEM Glock 19 15-round steel-lined magazine body with Shield Arms' precision-machined +5 billet aluminum magazine extension, this package increases overall magazine loadout to 20 rounds without sacrificing factory feeding geometry or slide lock reliability.
Precision CNC-machined from aircraft-grade 6061-T6 aluminum and finished in a tough anodized black coating, the +5 extension incorporates an easy-access index pin system for toolless maintenance and field stripping. Paired with a high-tensile 11-coil extended magazine spring, it delivers steady upward cartridge pressure to support high rates of fire and reliable last-round slide lockup.
Factory pre-installed and ready for immediate duty or range deployment, the Shield Arms 20-round extended magazine offers high-capacity firepower in a clean, durable setup built for tactical drills, competition, and home defense staging.
