I've been having a lot more trouble seeing My revolver sights in focus lately. But the small arp. peep sight, & hooded gold bead on the .222, seems to actually clear things up for Me, almost like putting on glasses or something.
I've been thinking, I'd like to try a ghost ring insert blade in the rear sight of the pistols, & see if it helps. I do have a Millett Red Dot on My 7 1/2" .45 LC right now, that I installed before last deer season, but really do not like scopes on a revolver ! It just kind of ruins the whole concept of carrying a revolver in the first place. A revolver should be kinda compact, & easy to carry & use.
Another thing I may investigate, is a small stick on for your eyeglasses, that has a small peepsight like hole, & is supposed to correct your vision for shooting. Has anyone seen or tried them ??
