My Brother had one in 9mm Luger plus the regular barrel. He said the mags fed fine but I would be a little worried as the overall length of the Tokarev is quite a but more than the 9mm.
After he died, I guess his Son has it now and he too is a shooter.
I wonder if anyone has done any experiments using say 147 gr. bullets loaded way out which should leave plenty of air space for powder. A person should be able to get some near magnum power loads. Of course you would have to separate them from your other 9mm as they would not fit in a regular mag.
I am pretty sure the pistol would take the power as the CZ ammo was quite a bit hotter than Russian Tokarev.
I know you can swap barrels for 9mm, but I don’t know why you would, when Tokarev ammo is so damn cheap and plentiful.
I’ve heard reliability might suffer, since the shorter 9mm has to jump forward out of the longer mag, but I have no personal experience.
