Shield Arms DS-20 Glock 17 9mm 20rd Magazine

The Shield Arms DS-20 holds 20 rounds of 9mm in a steel body that sits flush in a Glock 17 size frame. That is 3 more rounds than the standard 17 round magazine in nearly the same footprint. It works with Glock pistols and Gen 3 clones, and it is listed to fit the Glock 17, 45, 19 and 26; in the shorter grips it extends below the frame.

An over insertion stop is stamped into the steel so the magazine seats at the right depth. The finish is nitride, and the D Series works with Shield Arms magwells.
