Welcome to Johnson County. I can heartily recommend Elmore's, they are almost Greenwood PD's "unofficial" arms supplier and armory. A real bunch of good guys there.
Ditto on Substance-P's comments.
I'd also recommend you trek to Beech Grove Firearms and check them out. Very nice staff and good prices.
After that, you'll want to take a field trip north and west and visit AAC in Mooresville, Bradis in Camby, and Plainfield Shooter's Supply in ....in....wait, I'll remember....oh yea, in Plainfield!
