The Tokarev is a safe, functional and fun pistol. Not one I would carry concealed, but a great gun. The main safety on this or any pistol is between your ears.
You may or may not know, that there are 9MM barrels available for these pistols. They seem to be somewhat scarce today, but I bought one from SARCO last year. The X25 magazines work with the 9MM just fine. To swap from X25 to 9MM is just a matter of field stripping and swapping the barrel. (about one minute for me) The one I got worked fine with the existing barrel bushing and barrel link. It is like having two pistols in one.
