Included with my new Perazzi was a large tube of Perazzi grease, which I assume that Perazzi intended that I should use on the gun. When I looked at the "Giacomo sporting" website, I found in the FAQ section that Giacomo says to use oil instead of grease on the gun. I have seen where a lot of folks on trapshooters.com refer to Giacomo as the ultimate authority on Perazzi shotguns. So what am I to do....use oil or grease to get the maximum life out of my new Perazzi? Could some of you long time Perazzi shooters give me some advice on this issue?
