Nice sights, not real bright for brand new. - Ameriglo Rear Tritium Night Sights Glock 43 Yellow Tritium With White Outlines GL-431R

Could be brighter. After the guy at my local gun shop put them on for me he offered to take them back off because they weren't very bright. He said since they were brand new they should be much brighter. They've good in the dark , low level light not so much glow, but the white rings work good in daytime.
