Does anyone have one of these in a 20" and if so how does it shoot, Is the magazine a problem and if so did Savage replace it with one that works, Or is there an aftermarket that work better. When did you get yours as I cant find any around here, Have one on order but have no idea whether it will be a couple of weeks or 3 mo. The last gun I ordered took 6 mo to get. Appreciate any insight on this.
