Shield Arms +5 Base Plate for Glock 17 – Black

This Shield Arms base plate extends your Glock 17 magazine capacity by 5 rounds, converting a standard 17-round magazine into a 22-round capacity without compromising reliability. Designed for shooters who want more rounds on tap for competition, range training, or home defense without moving to a bulkier extended magazine body. The added length provides a fuller grip surface while maintaining a clean profile.

Machined from billet aluminum with a durable black anodized finish that resists wear and corrosion. Drop-in installation requires no gunsmithing—simply disassemble your Glock magazine, swap the factory base plate for the Shield Arms unit, and reassemble with the included extended spring and follower. Compatible with factory Glock 17 magazines and most aftermarket Glock 17 pattern magazines in 9mm.
