Shield Arms S15 Gen3 +2 Glock 43X/48 9mm 17rd Magazine

This is the Shield Arms S15 Gen3 steel magazine with a Shield Arms +2 extension already installed, for 17 rounds of 9mm in a Glock 43X or Glock 48. The S15 body alone holds 15 in the length of the Glock 10 round magazine; the extension adds two more with a short step below the grip.

The extension is machined aluminum with index cuts that help your hand find it coming out of a pouch. Its floor plate opens for access to the spring and follower, so you can clean the magazine without pulling the extension off.
