I have had one of the older models (before they changed the "buttons") on an 870 for about 3 years. It has been through a lot of rounds....buck, slugs, birdshot. The battery cap is easy to crossthread...and the power can get turned on very easily in transit. It has held perfect zero through lots (gotta be 700+) of slugs and buck. I use it for deer hunting and it's awesome. This is with the original mount too. I still don't think I would use it for duty use just because of the "power button getting bumped" issue...
