i have some of these little super strong magnets stuck to my fridge.
i pried one off with a pocket knife and stuck it on my ruger.
it does not want to move around (i tried banging the gun on my couch to see if it would move)
i think i am going to paint it black and see how well it works.
after some web searching i found that i can buy all sorts of ring shaped magnets with different inside/outside diameters.
what do you guys think?
