At least the ones that got accepted by the royal armories worked! Some of the machining on this one is mediocre - off center and off kilters holes. The ones we had from the 1970s were generally better in that respect.
Indian built? Definitely hit or miss and need proofing in most instances. I had one before that was for "powder burn" demonstrations only. Very reliable spark but I could literally see the inconsistency in the barrel casting.... I would not have put a live round through there.
