Stainless frame, custom grips, trigger work, beaver tail grip safety, trillium night sights, wilson combat accessories....etc. what is a gun like this worth? i'm freinds with my dealer, and it was from his own personal collection, so he gave it to me for $700, did i do as good as i think that i did?
