Like it or not, when the chips are down and lives are at stake, an armed citizen can be the "first responder." People who dont like guns invariably rely on people who have guns when their lives are in danger.
I've got two of these extended grip mags, got them on sale from Springfield. They work great and add stability when shooting the XDS. I also invested in a couple of Pearce grip extensions for my two 5 rd mags. That helped a lot too.
