I use a MMC adjustable sight on my glock, red for the back and green up front. Great sight picture,snag free and rugged.Its about 5 or 6 years old and still bright.If I had to buy another one it would be a MMC.
I've owned several sets of Trijicons. Nice & bright I bought one set 6 years ago & although I sold that gun, I do get to visit now and then & the sights are still fine.
