Buy both! Cheap enough to do so.lol. In all seriousness, the m70a because they are a little more difficult to find. Newer imports has that ugly safety, older example are more true to the Tokerav design.
Np22 are everywhere. The fit and finish is a level below the m70a. However the ergos are much better. The m70a is kinda a no thrills type of pistol and much thinner and not as comfortable in the hand. I know people who will not buy one because of how it feels in the hand and the way it looks. There are slip on grips and regardless of how it looks, the Tokerav is distinctive and so, so iconic.
If I were to do it again, I would still buy the m70a first! When I bought mine, it was $250 but I see that the prices has gone up recently but then again, I bought my m305 around the same time and it was only $450.lol
