I have played with a number of them, as there are no shortage of them in the middle east. In the pic below there are a couple on my work bench.
They were likely a pretty solid and modern pistol in the 1950s, but by today's standards, not so much. That said they are a functional pistol and seem to run well on standard nato ball ammo.
No reason not to get on if you just want something unique to fiddle with on range days, but I can think of quite a few modern choices that I would pick beforehand for actual CCW use.
