My question now is: Is 9mmx18, which is noted on my gun, the same or compatible with 9x19?

Any help will certainly be appreciated.

Hello, and welcome to the forum. You picked the right place to look for info on your P-64. I too am new here, but already learned a ton from all the great members here.
No, the 9mm (9x19) Luger ammo is not the same as the 9x18 Makarov ammo. Do not try to use 9mm luger in place of 9x18 mak.
The 9x18 case is shorter, which affects how the round is chambered, fired and ejected, and the 9x18's bullet is also fatter, closer to a 9.2mm round.
Even if you could get 9x19 to shoot, there would be no accuracy with the smaller 9mm bullet spit out of the P-64's larger diameter 9.2mm barrel.
The 9mm Luger round also about 50% more case pressure than the 9x18 mak, which in itself could cause a very bad day if shot in a P-64.
