Gun Parts

Give your Glock 17 a purpose-built, metal-duty magazine setup that adds capacity, durability, and faster reloads in one clean package. This combo pairs the 18‑round Mec-Gar steel magazine with a JagerWerks aluminum +4 extension for a high‑performance 22‑round solution.

Features

• 18‑round Mec-Gar steel magazine body for Glock 17

  • Heat‑treated carbon steel tube with anti‑friction finish for smooth loading and reliable feeding.

  • High‑visibility green, high‑impact polymer follower for quick, easy empty‑mag checks.

• JagerWerks aluminum +4 base plate

  • CNC‑machined from 6061 aluminum with Type III hardcoat anodizing for a tough, duty‑ready finish.

  • +4 capacity extension with included extended spring to maintain reliable feeding under full load.

  • Tool‑less, ramped retention design (on current JagerWerks +4 pattern) for easy installation and removal while staying locked in during use.

  • 12 Coil Spring for +4 Magazine Extension included.

Benefits

• 22‑round total capacity (18‑round Mec-Gar body plus +4 plate) while maintaining a controllable, competition‑friendly profile.

• Added weight at the base for more positive magazine drops and faster reloads under stress.

• All‑metal construction where it matters for shooters who prefer steel magazines and robust aluminum extensions over polymer.

Ideal Use

• Carry‑optics, USPSA, and outlaw matches where higher capacity and fast reloads give a clear edge.​

• Duty or defensive setups that demand reliable feeding, easy visual checks, and rugged construction.​
