You'll get a bunch of different opinions here, and - essentially - the recommendations will be based upon some assumptions (such as what the poster might assume that you want the equipment to do well) which might or might not be correct.
Some people will want the highest-speed most-specialized (for IPSC) and most-expensive gear available. Others want versatility. And some want cheap.
Me, I'm going to suggest to you what I would buy myself, today, were I in your shoes.

For your Black Badge you'll want to have at least three magazine pouches and at least four magazines (although five or six would be better).
