Springfield Echelon 20-Round Extended Magazine

The Springfield Echelon 20-round extended magazine adds three rounds over the flush-fit 17-rounder using an extended polymer basepad. The extra length creates a positive reload index for tactical reloads and fills out the grip for shooters with larger hands, while keeping the same stainless steel body and numbered witness holes found on the factory flush-fit magazine.

This is the default extended magazine for home defense, duty backup, and range use. It is not compatible with the Shield Arms +5 extension, which is specifically matched to the 17-round body. For maximum capacity on the 17-rounder, combine with a Shield Arms +5 for 22 rounds; for factory-grade extended capacity, the 20-rounder is the duty-safe choice.
