I know there's only a few choices, P7, USP, P-series or HK45 but are you planning on picking up a backup or new HK with some of the cash coming your way? I was going to use my tax return for a down payment on a new truck until I realized there was nothing wrong with the paid off one I have. Duh! Then thought about a AR15... Pass. I'm pretty sure I'm going to get a P30L V3 since my concealed carry needs are met. If you don't have any debt or more important money commitments please share if you'll be getting a HK with some of Uncle Sam's bucks.
