the glock is mechanically superior, even if the mp is a good gun. the glock 'sear' is larger and interacts with the striker over a larger surface area. the mp has a striker return spring and doesn't strike primers with as much force. the mp rear sight needs to be removed to access the striker safety plunger, which is a extremely gay design. slide to frame fitment is much looser and rattles on the mp, and the mp trigger, at least on the gen 1 mp is like 7lbs of pure nigger.
