Under India's firearms laws there are some expensive red tape procedures for shipping "working" firearms to other countries. In addition, both the US and I'm sure, Canada, have higher import duties on "working" firearms. So for the Indian manufacturers to export them and the Canadian seller to import them, it is cheaper and less hassle all the way round to get them in as "replica" guns.
Indian made guns run all quality ranges from pretty crappy to very high end highly engraved modern firearms that sell for tens of thousands of dollars. In general, the Idia made muzzle loaders, tend to be on the lower end for fit, finish and materials. That said, I have two India made pistols that serve their purpose quite well. I have also ordered locks directly from M. Sikligar and for the price, they were nicely finished. Sikligar has been in business making muzzle loaders for 40-50 years. Decades ago, Navy Arms imported and sold double barrel muzzle loader shotguns from India.
There is some junk out there. One importer of Spanish muzzle loaders sold guns that were not fit to load and shoot. For a very few years some Chinese made flint muskets were sold in the US. Total junk. (around 1978) Blew up and killed people.
There have been a lot of stories around about muzzle loaders blowing up. I don't know of any documented cases of India made muskets blowing up. a few Savage made smokeless muzzle loaders have blown up.
A lot of folks truthfully say that if you want a historically accurate gun, don't buy India made. and to a big extent that is true. But a TC Hawken, was likewise not a good example of a historical gun, same for CVA.
