I'm with you guys! My first Baikal was a 16 ga. sxs with external hammers (1950's vintage, I believe). It's as well balanced and regulated as most makes. I don't recall putting it on a scale but, having hunted with it extensively, I'd say it weights in at about 6 lbs 12 ozs. I wanted to try my hand at refinishing stocks and I didn't particularly like the blond finish that came on the gun. The refinish was a lot of fun and turned out nicely.
Since then, I've bought the identical model in 12 ga and one in 20 ga. All 3 are on properly scaled frames, 2 3/4 chambered, and nitro proofed. All 3 function normally under all conditions, every time.
