I have a chance to buy a CIL model 607 3" mag which was made for CIL by savage arms , it looks alot different than all the other 607s and savage model 67s i have seen. it doesn't have the rounded trigger guard it looks more like a mossberg 500 . I'm trying to find out if i can shoot steel shot out of it before i purchase it as there are no places locally i can buy 3" lead shot shells. i believe its an 80's gun
