Guys, I've had green/green Meps on my G30 and G21 for a long time. They're finally getting dim and to the point I'd like to replace them. Right now I'm stumped, though. Green/green has always been bright and easy for me to pick up, but from the looks of this forum yellow/green seems to be the choice. Why? I have green/green Trijicons on my Sig P220. They aren't as bright as the Meps when new, and the ampules are smaller. I still like them, however. Now, after visiting this forum I see Ameriglo sights, and apparently the latest rage is yellow/green Pro Operators. Awesome. I'm thoroughly confused as to what to get now. Give me your best shot at choosing my new sights and WHY! Thanks a bunch!
