I think the NP-30 is a double stack 1911 which you may run into problem of after market parts.
+1. your grips and stuff like that are different because of the wider mag well. you MIGHT face difficulty finding aftermarket parts for it. I have a single stack, so I haven't looked into the aftermarket offerings for the high capacity versions. Kimber make a high-cap 1911 as well, so there might be some stuff!
