I’ve been using magpul cases for a long time as well. In the hand, the grip is good due to the raised lines of the design and the lightly textured surface. I find though that the phone will slide around a lot on surfaces as the material is more like hard plastic than a grippy rubber, if you will. When I was overseas a while back I got a rubber textured adhesive (specifically made for the back of phones, found it easy on amazon, but forget the name) to place on the back so I could set it down on metal surfaces in mil vehicles and it wouldn’t slide all over the truck.
