good point keith. as i have no plans to be in total darkness without some kind of light, will leave the trijicons on the glocks.
however, have seriously considered fiber optics for daylight shooting, targets, plinking stuff. my aged eyes need some help. i am now using red dots, but, they are enormous and holsters for carry are more of a bag. ok for hunting, but
if you know of a source for fiber optics that swap out on handguns, please pass it on. all i can find are for long guns.
