j4570 - Photos and Blah Blah....Medallion Hole is 0.560" in diameter.
The Ruger Sight I got (Ruger Front Sight For Ruger Single Six 22 Long Rifle,
Single Six Bisley 32 H&R Magnum XR13600 E-Bay) was very very LIGHT and
non-magnetic. I tried to scratch the underside for Gluing - it would not scratch !
So it was NOT Aluminum. I suspect it is a Carbon Fiber Composite......
The underside Curve a was so close to my Arminius that I decided (being lazy)
to Superglue it on after I mounted it with a Screw that I found in a bottle of saved
screws on my shelf - I SAVE everything ! I'm a Pack Rat & Hoarder ! Pays off !
The curved under surface very closely matched the pistol's barrel, so I decided
to screw in down tight (only one hole in the sight) and SUPER GLUE the sight on.
Ya - I know - can't let the barrel get very hot or it will let go. Might use that Red
Thread Lock Permatex glue on it if it ever does let go......
Click on the images, when they come up, press F11 (Full Screen) ! F11 to go back...
I blackened the screw with a Black Sharpie Marker.
Took the photos with a Digital Camera with +4 close-up lens, a strong LED Flashlight,
holding the pistol between my knees (unloaded).

PS - I am shooting 93 grain LEE Cast WW Bullets with 2.3 grains Bullseye.
At 30 ft putting them into a 12" circle - this gun is deadly !
