Hi All, I have an opportunity to pick up a slightly used GP100 (stainless, 4in barrel, newer production around 2010ish). It belonged to an elderly person who passed away. The person had picked up the gun (their first) in their golden years because of the felt need for some type of home protection since they were alone in the house. I don't know if the gun was ever really fired. I figure there might have been some test firing early on, but for the most part it was kept holstered in a drawer in the home. As far as I know the gun is in pristine condition. Asking price is $500. This price seemed reasonable to me, but I don't know what the going prices are for the GP100. Any help would be much appreciated.
