Depends on your definition of "gunsmith" and what type of work you need done to the gun. What do you need done?
I typically do all of my own work and stuff for friends, but not for business. Locally, I would suggest Indygunworks. Maybe Scroggins if you're going to travel to Martinsville. Otherwise, we are truly limited in the area of REAL gunsmiths in the Indy area. Gun shop employees with an "armorer" certification is NOT a gunsmith. If they guy doesn't OWN or AT LEAST have access to a metal lathe and mill, then you should slap them if they claim to be a gunsmith.
