After reading a few articles I pulled the trigger on mounting a Griffin Hill red dot mount on my SBH 45 Colt.
The mount went on with ease by just following the directions and taking your time.
The Burris FF3 will be here for the weekend.

Do you have to drill a hole in that mount where the pin goes through the original sight or is it already drilled?
I'm fixin to pull the trigger on one of these.

Switch from side to side alternating when drilling. |

That pin hole should be a game changer.

IMHO that ledge at the back of the mount is where the recoil game is played with these mounts. During recoil the gun drives backward while the sight tries to stay where it is, shearing the mounting screw(s). That portion of the mount that abuts the rear of the gun halts that "forward" movement if it is fit properly. Some manufacturers designed their bases as file-to-fit, others resort to shims. I honestly don't think the pin adds all that much in the way of mount integrity. Then again, maybe I'm missing something...

I COULD NEVER GET A FFIII TO HOLD ZERO ON A 7.5" 327 SINGLE 7 USING 2 DIFFERENT NO D&T MOUNTS, SAME FFIII ON A MODEL 97 IS DEADLY ACCURATE ALL THE TIME. ME, I AM THINKING/HOPING THAT THE TIGHT FIT, SHIMS AND THE PIN WILL KEEP THE MOUNT ZEROED. - 45MAN |

As stated above, the majority of stresses encountered by the mount are shearing and compressive. The recoil lug, as long as it is tight to the frame will bear the vast majority of the loading during firing. This was specifically why when I mounted my red dot a little forward on my BFR that I used epoxy between the mount and top strap. Lack of a recoil lug necessitated something other than the screws be used to absorb the shearing stress of the recoil. singleactions.proboards.com/post/348989/thread |
