Regarding PSS, which is a very good shop, just be sure and check their hours before you go, as last time I looked they were open Tuesday through Saturday from 11 AM - 5PM. Can be a bit tough depending on your work schedule and where you are coming from.Depending on what side of town you are on, you might check out Plainfield Shooting Supplies. Bob generally has great prices and a good selection. He used to have a better selection, store ha seemed ‘less full’ the last few times I’ve been in.
I’ve not been to Beech Grove Firearms in awhile, but they always had a very large selection of modern handguns. Good people in there too. Not much help on the north and east side of town.
