The SP and SR primers are same size, but with different cup thickness/hardness and different amount/brisance of priming compound.
Large Pistol and Large Rifle primers are different in height, and cannot be interchanged.
I would not use SR primers in 9mm for the following reasons:
.You need to reduce your load - the SRPs will produce more pressure, which may result in primer leaks and other pressure signs. Ask me how I know.
.SRPs need a harder strike due to thicker/harder cups, your loads may be less reliable
