    Glock MOS vs 3rd party slide milling

    I have heard that the MOS will run optics higher than a milled slide. Can anyone confirm this? If so, will suppressor height sights still be visible through a red dot on an MOS? Will it be like a lower 1/3rd co-witness? How usable will they be? What do you guys prefer between the two?
