I transfered a Norinco .22 semiauto pistol for a friend some years back. A copy of the Walther Olympic pistol,,, TT-22 model I think is what Norinco called it.

We took it out and gave it a work out and though a bit rough around the edges,,especially the grips, it worked just fine and had no problems at all.
It was a used pistol with some wear but didn't seem to have suffered any problems from the normal use it had seen.

Definetly not in the same quality of fit & finish as an original Walther,,but then it was never ment to be.
It worked 100% reliably as it was intended to do w/ HS ammo.
