Loose sights

[Canteathorns]

I have a set of tru glo universal sights on my 870 . They are on tite but loosen up after a couple of shots.i was wondering how can I keep them tight or should I just go with williams universal vent rib sluggers sights but they clamp on to . Heck I don't know ! Advice please ?

Happend to me a couple of times I placed a small dab of clear Silicone under each. Helps absorb the shock and can still be removed. Works well  with either the "snap on" or "set screw" type.

If you decide to go with a more positive mounting sight , don't overlook the Tru Glo magnum gobble stopper PRO Series.   I have a set on a BPS and a set on a 935 Mossy...they use two allen screws on each side to "clamp" into the side of the rib...if you have a vent rib gun.

I really like mine and they offer windage and elevation adjustment.
