bought a pair of nf sights and quickly returned them, i view them as a 2nd tier night sight.
have trjicon hd(s) on all my other pistols except for my glock 43(s) which ride with ameriglo agent(s) because the hd model for that particular pistol are like tiny swords ready to stab and cut you up.
trijicon hd, ameriglo agents, and sig xray 3 sights are the only brightly colored sights i buy.
thumbs down to night fision and truglo tritium pro(s)
blackout serrated rears are a must
