Believe its a 1982 Italian made
I just replaced the locking block and recoil spring with gen 3 parts from Beretta and have not put rounds thru it.
This has definitely been used as you can see from the wear. Lanyard loop is rotated 90 degrees unlike the new generations.
G.f. markings when issued to Italian Police
1791 leather holster
Pachmayr grips
3 mags total all 15 rounds
