Just wondering... Can a Glock be used in close-quarter combat without damaging the pistol? If so, what part of the Glock can be used to strike another person (such as a head shot)? I know the adjustable sights would go amiss no doubt. Just wondering if the slide has been tested in such a way. I'm also completely unknowledgeable as to how the polymer frame would withstand such a thing. Just wondering. I mean, if a man has to, he has to... I'm just wondering if you'd still have a functioning weapon afterwards or if it would totally trash the thing (as in having to be thrown away & replaced).
