WOW! Thanks for all the info. I knew it was a 3" but it had not occurred to me (my shame; a metric Canuck too!) that the "76" may be millimeters which is almost exactly 3". So, it appears to be of 1975 vintage. Any ideas regarding a model number or name? There is not a lot of engraving so I'm guessing it's not one of Beretta's exclusive guns. I'm dying to try it out at the turkey shoot on New Years day. Thanks again for all your help.
Cheers;
