Baikals, yeah, I love 'em! I bought an IZH43 (20", cylinder bore, double trigger) in 1999 and am still shooting it. I have some other shotguns and don't practice, so it has a mere 3000 rounds through it with no problem. I recently bought a lightly used one at a great price (because the owner had antiqued it, horribly
) because they are a little hard to find now and I figured a spare might be nice. The newer one is also an IZH43 but it has screw-in chokes.
These Russian made guns are hell for stout. I'm not worried too much about wearing it out. When they are new, after you open the shotgun all the way to dump the empties, the barrels close part way and make it hard to reload. By pushing the release lever to the left after it is all the way open, it will stay open. This is easy to do if you are right handed and load with your left hand. I just got used to doing it that way for the first year. Then Coyote Cap came down to Texas for a shoot and I handed it off to him for an action job. Back then, the cocking levers (visible on the front of the frame when the barrels are off) needed to be re-shaped to allow the barrels to stay open. A few years later, a guy named Papa Dave started selling custom made cocking levers that can be installed. I'm not positive if he is still making them, but I think so.
A few years after I had mine, Remington started importing some of the Baikals, but no longer do. So you might find one so marked.
