For those who purchased a G17 Gen 5 MOS , what were the main reasons why you decided on this model ? I currently own a nice G17 Gen 3 with night sights and finger grooves are fine with me . The G17 Gen 5 MOS is mainly appealing to me because of the new Glock trigger , the marksman barrel which has shown to be more accurate (especially at greater distances) and the MOS cut out for Halosun SCS red dot made for the Glock MOS cut out . I don't care about switching slides , so the only other Glock in the running is the close G45 MOS *which I do not plan to carry) . The G45 is said to balance better in the hand than the G17 - but individual opinions may vary on G17 / G45 hand balance ... Your replies and experiences to the above ?
