Maybe you forgot to Read the Rules on posting for sell firearms? How much are you asking for it? Is it in Pensacola?
Did you Only shoot 1 round, 1 tube or shot it all day "once"?
If you shot only 1 round, what happened, did it break, jam or kick too hard?
Did you clean it after that "fired once" time?
Is it Blued or a Golden Boy?
These are important questions so please help with more details.
Got any pictures? Can you post a few? It would help.
Oh, and welcome to GCGF.
