Between the stock Glock sights, Meprolights and Heinie slants, I'll take the Heinies. The Mepros are great, bright, all that. The front sight is just too wide. I feel like I get a better sight picture with plain old serrated front and rear Heinies. I've got bad eyes, but I don't find myself needing the "race cut" rear. Best 47 bucks I ever spent on that Glock.
