More of the 75's had the sawed off(20") barrels if you're into that sort of thing. I own several of both 75's and 85's. I prefer the 85's for a variety of reasons. More open grip, claw controlled feed which reduced the feed angle for smoother operation, shorter bolt handle and on wood stocked models about 1/2 pound less weight. The new soft touch stock of the 85 finnlight is very well made and I prefer it over the 75 stock.
