I have a Norinco 9mm. It says 213 on the slide but certain things like the safety not being backwards lead me to believe it's actually a converted 54-1. It shoots with excellent accuracy and I really like the thinness of it but every once in a while when you pull the trigger the hammer stops just short of the firing pin. Still a very good plinker. It took a while to locate mags for it but I was able to. Over all I really like the gun and will always keep it. I just wouldn't rely on it as a carry weapon.
