We bought several muskets and pistols made in India when I was working for my County's history museum for use in various reenactments. We had an extensive collection of reproduction muskets for use in living history programs and I was the museum armorer in charge of maintaining them. We had several Brown Bess muskets made in Japan, Italy, and India. We also had flintlock pistols made in these three countries as well. We bought from TOW, Middlesex, Dixie, and Loyalist over the years.
With the Indian made guns, I did have to drill touch holes on some of them and do some fine-tuning on the locks. I also pulled their breech plugs, inspected and proof-tested them to my satisfaction. For the price, the Indian muskets and pistols were fine, and we could buy two for the price of one made in Italy. It is true that the fit and finish is rougher, but reenactor guns get a lot of hard use. It was hard to watch one of our $1000 Pedersoli guns get slammed on the ground and have a 300 pound reenactor fall on top of it!
I spent a lot of time repairing the Japanese muskets, mostly re-hardening their frizzens, tumblers, and sears. Broken stocks on the Italian guns happened occasionally, but we never had one of the Indian musket or pistol stocks crack or break. I believe that is because they are made of Teak which is strong and fibrous (but looks like it was carved from an old 2X4)
I have seen some junk muzzle loading "guns" from Spain, Japan, Belgium, Italy, and India so always bought from reputable dealers like the ones I mentioned.
