I do service and help with the Perazzi (as in sales); however, I note that you are out of my service area. If you would like, I will give advice. Many of my customers shoot the 28 and .410 in sporting events. I like the 28 better. If you want to talk to the master,then call Giacomo 315 336 1356,or Giacomo Sporting,Inc 6234 Stokes Lee Center Road,Lee Center, New York 13363,or FAX 315 336 0260 (he is also on the Web)and use my name as a reference. Some like the small frame MX 8 and others like the small frame MX 2000S which has the barrel selector on the safety slide. BTW, the barrels are not in inches, but in centimeters.You are looking at 75 cm. As a production O/U, it is the tops. Bill
