TGI in Knoxville usually stamps their imports on the bottom of the slide. I have a few CZ-82 guns from them stamped on the underside of the slide rather than the "Billboard" stamps from other importers.
Highbars, was your P-64 well broken in? I just got mine from IO Inc up in Monroe, NC and it looks like it was only test fired at the Radom factory. It is a 1977 mfg. I am going to run about 100 rds thru it to see if it helps break in the action a little.
Real nice 1967 P-64 that you have there. Did the manual come with the pistol?
sgt p. yes it was already broken in, I picked it up from a good friend of mine for $100, I shot it a few times befor he would sell it. it's a 1971 and yes the manual came with it
