I'm not new to Glocks but I am the first time owner of a new G20SF. Finally took the leap and picked one up at the show yesterday. Real excited about it but had a question for the experts. I replace the sights on all the Glocks I buy with either Warren's, Heinie's, or 10-8's. Since this isn't going to be a carry gun I'm debating on installing a fiber optic front. I'VE never had a FO front sight but I understand they are not the most durable sight. I figure if I have to replace the fiber or completely change out the front it won't be a great big deal. Does anyone know how well a FO front will hold up on a 10mm? If it's going to be an endless changing of fiber rods I may just go with a brass bead front sight. For what it's worth on this one I was putting on 10-8's. I understand they're FO front isn't as bright a most but is more durable. Thanks for any input.
