because the sd series has been around since 1982 and has premiered in so many movies such as die hard,blood diamond and rap videos that everyone thinks they're the best.Till a sd is dropped from a airplane,dropped in the ocean,and/or fired in a swamp.....you can't compare the two.Glocks have a reputation that is hard to beat but lets not forget the most successful propaganda campaign in history where the romans said the barbarians were the most crude and unsophisticated civilizations in history....although it was never true we still believe that they were to this day.lets not reach conclusions till the sd has gone through the same torture tests the glock has gone through,only then will you have an equal comparison.
