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.
Mine's actually a Italian Pedersoli, and generally considered a fairly decent reproduction. I haven't looked into when it was made but guessing later 1980s or 90s.
