Many things are possible but maybe not too smart to do. 46,000 P.S.I versus 49,000 P.S.I., it might be possible to do either of them on a 16 gauge frame, but I wouldn't want to shoot either of them very much. I tend to be more conservative in what pressures I will build a conversion gun with. You may do as you please. At least I will not have to worry about either of them coming apart. Bob
