JP, with that many shells through it, perhaps you can answer some questions I have about the Baikal guns.
A few years ago I handled a new one in a store. The pivot felt way too tight, and stiff. The stocks felt a bit chunky and gave the impression that the forearm section might work loose.
Bear in mind that I bought my Baikal as a USED gun at a gun show. I have no idea how many rounds were through it before I bought it, or what manner of gunsmithing may or may not have been done to it by a previous owner. That said, the gun did not appear to have many rounds through it at all and I doubt if it has had any gunsmitthing done to it.
I'm not sure what is meant by "clunky" in terms of the feel of the stocks. I have no complaints with mine. One of the reasons why I wanted this gun, among many, is that it fits me as if bespoke and it feels good to me on the swing. My Baikal does take more force to break open than the Ugartechea 20 bore side by side that it replaced did, but my "Uggie" was an extractor gun. The Baikal has selective ejectors and the ejection of the spent shell is VERY FORCEFULL. It will kick the empty hulls out 10 or 15 feet behind me if I don't catch them in my hand. Some of the "stiffness" in breaking the gun is undoubtedly due to stout ejector springs. I like the forceful ejection and the "stiffness" isn't overy so to me.
How is the pivot, will it drop open when unlocked or is it still too stiff to do that? Has the forearm remained tight or is there a slight movement in it?
The hinge pin remains in great shape, as does the "hook" on the monoblock. When the gun is in a cocked condition, it does not "drop open" when the top lever is thumbed. My Uggie didn't "drop open" when cocked, either. I had it for 25 years and put about 25,000 rounds through it and it still didn't "drop open". When cocked, the barrells on the Baikal will drop ALMOST open, but the bottom of the extracted shells do not clear the fences of the receiver. My Uggie was the same way, and frankly, I prefer that to completely dropping open. The gun is rendered safe, and my hunting buddies can see that clearly, if I have to tend to a dog or something while out on a hunt, but I don't run the risk of inadverdantly dumping one or both shells on the ground because enough of the rim is captured by the fences to keep the rounds extracted but still in the gun. My Baikal was like this when I first shot it. Nothing seems to have changed. It hasn't gotten noticably "looser." But I am okay with that because I didn't fnd it to be objectionably tight to begin with.
My Baikal is a single selective trigger gun. I THOUGHT I wanted a double trigger / extraction only version (as my Ugartechea was) BUT in using the single selective trigger, I have come to like it quite a lot. I haven't had any misfires or experienced "doubling." So far, the single selective trigger has been totally reliable. Also, because of the Model 21-like location of the barrel selector, I can switch barrel firing order with a sweep of the trigger finger during the mount and with practice, this has worked out for me as well as double triggers in terms of quickly choosing between available choke constrictions when making a shot.
