I have a build it yourself derringer kit that I bought on gunbroker.com.  I can't link to auctions, but if you do a search on derringer there you will see several.  What are the legal implications of finishing the kit?

Before you tell me what a piece of crap these guns are, I already know.  The main purpose of the kit was to have a project to do with my 8 year old son.  I hope that I don't have to make it inoperable when it is finished.

Any ideas?

Thanks,

Actually, the one I got is a .22LR 6-shot.  You have to manually turn the cylinder between shots.  Safety is not a problem with us.  It was drilled into my head even before I started shooting at 5 and of course I passed it on to my son.  He has nothing but respect for firearms.

Thanks for the info guys.  Right now we are still filing down weld marks and preparing the frame for bluing.

Very easy except for one step.  The breech face needs to be welded to the side plates.  I had to have someone else do this because I don't have the equipment or expertise.  It came back pretty ugly (but it was free so I can't complain) so I am still filing it down.
