The problem is always whether or not the US will allow importation of these from Russia, and even if they will, of getting one out of Russia, as it certainly is not profitable for a company to ship just a few items to the U.S. In this country (the USA), despite all of the ridiculous efforts to basically and eventually outlaw virtually all gun ownership here, there is still, at least at the present time, little market for less-than-lethal firearms here. We can still have pistols that fire lethal ammunition in most places in the country, even if they make you jump thru hoops to get them.
Unfortunately. In my case, I would obtain each and every version of the Makarov in the various “special” calibers, like 9 mm PA, .45 Rubber, etc. I doubt, though, that it is even possible. Aside from the fact that US authorities don’t allow much in Russian, Chinese, etc. weaponry directly from those countries to enter the USA, there is also the problem that depending on what or what not has been done to the frame of the pistol, the “legal firearm” in this country, even with no other parts in it. If the frame (receiver) can be easily converted back to a real lethal firearm, then it is “a gun” regardless of what the rest of the parts make it in reality. For the cartridge collector, the availability or non-availability of the gun in their country often determines whether or not the ammunition is ever made available. Then, the only way we can add the cartridges is if another collector in a country where they are widely sold can supply any (bringing some to an American show, or an American getting them at a European show) and then only if BATFE will allow that particular caliber, manufacturing source, cartridge type, etc. into the country.
