Looking at a Mossberg 590 Special Purpose 20 gauge, but not 21 for a few months. So my question is, once I turn 21, where can I get a high cap. mag extension? Couldn't find any on mossberg's website or a couple others. Also, the specific shotgun I found already has a grip-pump on it (idk the technical name) where you pump it with your fist upright. Where can I get just a reg. forearm for the thing? Again no results on mossberg's website or some others.
