I don't have a problem sellnig or trading any of my guns except one. My Beretta 92FC was issued to me on the job NIB in 1988. When I retired in 1991 I bought it and only once let it slip away. Gave it to my son but soon realized that I really wanted it. So, bought him a new Beretta and got my old 92 back. Sits in the safe today, functions just as well as it did that day 25 years ago when I first got it. All paperwork and box reside with it. other than that, I'll sell or trade any of them, depends on what catches my eye. That's the fun of it.
