The XIX is a domestically made copy of the VII .50AE. IMI changed some of the dimensions from the .357/.44mag VIIs to fit the .50AE. When manufacture was handed over the .50AE VII was used as the base for the XIX DEP platforms.
So...if you have a .50AE, whether version VII or XIX, you have the same gun (expect, of course, the VII is Isreali and the XIX is US). XIX parts will not fit on .357/.44mag VIIs.
