Anyone knows where could I possibly purchase after market fiber optic front sights for a glock17 in Manila? Are there choices available as I am looking for one that has a front sight height minimum of 0.285". Another question is, though I have searched this forum and could not find an answer, which sight width is better? Is it better to have a thin blade say 0.105" or 0.125" or a fatter blade? Wanna kill these ads? We can help!
