It depends on their relief cuts for the mainspring assembly. Newer models have a plastic mainspring seat with a different spring and strut, than yours does. You have the older style "spur" hammer. I found when I initially tried to convert my '90 model to the newer polymer 2 piece grips, I needed to replace my hammer with the newer style hammer with the rounded spur rather that the pointed spur. Also your hammer doesn't have a reset spring which will be needed, if you convert to the newer style hammer.OK quick question, will set of grips off of a new P220 elite fit on this gun?
