Got a set of SGT sights mounted on my 870 a couple of weeks ago, just in time for hunting season, so I went out to the range to sight it in with slugs. I have a benchmaster rest, so I set it up in that, with a target at 25 yards. Got all set, and squeezed one off. I noticed as the gun was recoiling that the empty went flying off to the right ("hey, wait a minute, this is a PUMP shotgun, WTF?"). Loaded another single, squeezed it off - same thing, there goes an empty red hull off to the side. At this point, I noticed that slug holes are easy to see at 25 yards, and that I'm hitting just a little low. Moved the rear sight up one groove, it was on for azimuth. Fired one more single at 25 to verify (Yup, there goes the empty!) and then one at 100. I finally figured out that because I wasn't holding on to the forearm, it was free to cycle during recoil, thereby ejecting the empty hull. It sure had me going for a bit though. So anyway, I got set to fire my next shot at 100, and found that the front sight had departed the barrel during the 4th shot. Finally found it in the grass about 15 feet behind the line, and that was the end of the session. Took the whole thing back to the smith that did the installation, they claimed to have followed the instructions to the letter (and to their credit, it did look as though the epoxy had just not been able to grab the sight), and they went ahead and installed a screw through the sight into the top of the barrel. Has anyone else had problems with the SGT front sight not wanting to stay on?
Oh, that fourth round hit at 100, about 4 inches low. I might just get to liking this thing, if the sight will stay put.
