The bottom metal will have no effect on how the safety works,as long as it is from a 95 or 96.. The 95 and 96 Mausers are basically the same dimensions. The fact that follower blocks the bolt is only due to the shape of the follower at the back, allowing it to rise higher with an empty magazine to block the bolt.
I don't have a 95 so can't say for sure, but I doubt that a 95 trigger is different than a 96.
