Lacking all the details, it's hard to say what's going on.
Honestly, the best bet is to just ask for the return of the gun. Keep it positive and out of the mud. No good will come from getting into a pizzing match and dragging stuff like this across the interweb. Give the 'smith a chance to exit the situation gracefully and move on from there.
Being the bigger person in a deal like this is hard but better in the long run.
Hope it all works out for you, sir. -Al
