Magazine Spring for Glock 17 / 19X Extension - Replacement Extra Power Spring

The Magazine Spring for Glock 17 / 19X Extension from Terran Gear USA is a direct replacement extra power spring designed specifically for magazines equipped with the ZR Tactical Solutions +5 basepad (or similar Glock 17 / 19X compatible extensions). This high-performance spring ensures reliable feeding, consistent function, and long-term durability when running increased capacity setups on your Glock 17 or Glock 19X.

Manufactured to exacting standards, this replacement spring matches the extra power specification included with our popular +5 magazine extensions.

Ideal for competition shooters, trainers, or defensive users who demand dependable performance from modified magazines.

Use this spring as a replacement when your original extension spring shows signs of wear, fatigue, or reduced performance after thousands of cycles. It installs easily during magazine disassembly and reassembly, helping maintain peak reliability in your high-capacity Glock magazines. Pair it with OEM, KCI, or ETS 17-round Glock magazines fitted with the compatible +5 extension for optimal results.

Commonly Asked Questions

   It is designed as a direct replacement for the extra power spring used in Glock 17 / 19X magazines equipped with the ZR Tactical +5 basepad extension.

   Disassemble the magazine by removing the basepad and extension, replace the old spring with this new one, reassemble, and function-check by loading and unloading several times to verify smooth operation.
