One of my neighbors walked up to me yesterday and told me he went to a gun range yesterday for the first time. This guy is in his early to mid sixties and asked me what I thought would be a good first handgun for home protection. At the range he shot a G17 and now seems hell bent on picking one up. My first thoughts were to recommend some type of revolver for the home for starters, take a few classes, and then work his way up to using that G17 for home protection once he's more familiar. What would you recommend???
