Nice, that covers a lot of different categories for the money.
Actually, how much is the LC9 running with a laser? The laser might cause you to go over budget unless you are buying something else that is used.
Also consider your ammo/accessory costs. It might be better to go with something as follows:
AK47 w/ 5-10 spare mags + sling
Mossberg w/spare shell carrier
Glock 19 (or whatever caliber you'd like) for carry w/4-5 mags. You'll need a cc holster too, which will likely run $50-100.
500 rds 7.62x39
500 rds 9mm + 50 rds SD ammo
Remainder on shotgun ammo
