Good thought. Years ago whilst traveling on the hippy trail I went to a village called Darra in Pakistan's NWFP. Darra's claim to fame is that it is full of gunsmiths who can copy any weapon.
All you need to do test fire anything is buy the ammunition and the testing range is on the roof, or out the back. Whilst fireing there's always a crowd of children fighting over the brass ass soon as it is ejected.
