Sorry if this has already been discussed guys. I just picked up a used 935 off of a buddy of mine, he bought it used so he isn't of much help, and neither is google. I'm going to try to attach some pictures of the front bead. It's a fiber optic piece about 2" long or so (nothing unusual there) but it stops against a "horse shoe" piece that has a hole in each end of the horseshoe. Can someone explain what that horseshoe piece is for please?
The only thing I can come up with in my mind is if the gun is shooting high you could place the fiber optic in that hole to lower the pattern but that's just a guess.
I'm going to try to get three picture attached to this message so hopefully it works.
