The Shield Arms DS20 Combo is a starter kit that puts three 20-round steel magazines and one steel mag catch in a single box. The magazines are built for 9MM and fit Gen 4/5/6 Glock 17 pistols, so one kit works across all three generations. At 20 rounds, each magazine holds three more than a factory magazine, which keeps you shooting longer between reloads.

The kit includes one steel mag catch, the catch the DS-Series magazines are designed to work with, so your magazines and release are matched from the start. Each magazine has a stamped over-insertion stop that limits how far it seats in the magwell. The magazines are steel with a black nitride finish, and a lifetime warranty backs the set.
