Shoot what you have and borrow what you don't. I spent thousands of dollars on stuff I replaced later. It will take 50 matches and 50k rounds before you really know what you want anyway. If you have literally no gear then start with this:
Sturdy belt
Taccom Load 2 caddies (dual load 16 vest thing tim makes is the cheapest)
Cheap Kydex holster and mag pouches (2 pistol 1 rifle)
Whatever used glock/xd/m&p you can find used in 9mm... Full Sized guns only
Stag, doublestar, etc "3gun" rifle. Or any ar-15 at all, If it has irons shoot those, if not look for a used burris mtac, tac30, millet dms-1, etc...
Benelli m1/m2... try and find one used.
This will get you playing the game with nothing holding you back for a long time. As you get better you can add triggers and barrels and widgets to the rifle, pistol, and shotgun and end up with a world class rig if you want. Or you can sell them for almost what you have in them. You don't need 10k worth of gear to play our game. Just be warned, it's more addictive than crack!
The sooner you get to a match the better... Like the yuppies say, "A year from now you'll be happy you started today".
