Have you considered On Target, which is on MD Route 175 just outside the Rockenbach Road gate of Fort Meade? Their prices are decent and you can rent their guns to see which one(s) you like best. For one rental fee you can try out as many of the guns as you want; you just have to purchase their ammo to shoot though. I've found the staff there to be rather friendly as well and are willing to help new shooters any way they can.
