This is the ProMag Springfield Echelon 9mm 32-round extended magazine. 

Looking for an affordable and reliable extended magazine for your Springfield Echelon? If so, look no further!

The heat-treated steel body features a black oxide finish, which together delivers superior corrosion resistance and durability. Internally, a chrome silicon wire spring and an injection-molded polymer follower keep the magazine feeding flawlessly. 

To finish the magazine, an impact-resistant polymer baseplate will allow you to rest easily when dropping your mag during reload drills. Your Springfield Echelon can double as a home defense and range gun, both of which would benefit from having more ammo ready!

Note: this magazine is compatible with both the Echelon 4.5F and 4.0C.
