Check Outdoorsman, Copperhead Ridge, Ft. Liberty, Elmore's, Honey Creek, Beech Grove, Atkinson, and US Defense Solutions. . Copperhead Ridge, USDS, and Elmore's are the most likely, with Outdoorsman, Ft. Liberty, and Honeycreek a very close second. Call around and ask!
I don't remember seeing a big selection at USDS, Elmores used to have a lot but the last time I was in there they had low inventory on everything, that and the smoke lol. Copperhead and Liberty are too far out of the way, Elmores is probably the best bet. The purpose of the post was to try and avoid calling every gun store in Indy lol.
