Let's not kid yourself, you wanna buy TT33 because it is one of the cheapest guns on the market, and you imagine that you will save money this way.
It is NOT a good first gun, as a beginner you have a lot to learn, and TT33 will not make learning any easier.
In fact, you might lose interest in handguns if this is your first gun, because acquiring necessary skills to be an effective handgunner will be needlessly complicated.
I own TT33 and like it a lot, but its intended use (in Canada) is fun plinking for an experienced shooter.
Also, surplus ammo is prohibited by most indoor and some outdoor gun clubs.
