Has anyone here ever ground off the front sight and replaced it with a bigger one? New sight would either be glued on or machine work done on slide to put on a new sight depending on what kind was bought. Or, as dumb as this sounds, leave original sight on and mound some JB Weld on it and file it to size that can actually be seen by 62 yr old eyes with tri-focales. Any suggestions, even funny, are appreciated as always. Thanks guys.
