this is my first post here. i know questions about which sights have probably been done to death. but i need some info and could not find it on here by searching. i am legally blind and am looking for some night sights for my glock 21. i have used mepros and trijicons before but i always have the same problem i can not see the front sight during the day. i am thinking about getting some ameriglo's and was wondering. is the white outline on their front sights easier to see? i know the XS big dots would work. but i have tried a few pistols with them on and they mess with my eyes also. they are so big they blur the target. any info i can get will be greatly appreciated. i can not afford to try different sights so it is kind of a get it right from the start situation.
