Anyone have any experience with surplus Beretta 92S’s coming from Italy? I’m seeing some fair prices on them and just want to make sure I’m not getting into a clunker. The lower prices seems to come from visible wear on the guns, resurfacing the slides a few decades ago, and an odd mag release button location (located at the bottom of the grip). Is there anything I should be aware of? I’m seeing the following slide resurfacing types, none of which I know anything about: Burlington Oxide Blue/Oxide I can see the visible difference between blue and burnitron (blue is shiny, burnitron is matte). Any appreciable difference between the two? Any advice is helpful. This will just be a fun gun for the range.
