Madcap,
Its a moot point, to the point, you happen to need to do it.
Im not advocating it as a normal way to carry the gun either, as Ive said before, and I "normally" do carry using a holster, but there have been times when I did have another along, in a different capacity, and it was not in a holster.
My main point in bringing it up is, you need to prove to yourself, that what youre hearing on the internet, and other places, is in fact correct. You ALWAYS hear, and more often than not, from people who dont even own one, that Glocks should not be carried without a holster, yet how many who tell you that, actually know for a fact its true? Im simply saying, prove it to yourself, that the way you think you might carry it, is in fact, unsafe. The only way to really know, regardless what others might say, is to do it. And that goes for anything, not just Glocks.
Over the years, Ive personally seen more safety issues with things like 1911's and SIG's, than I have Glocks.
It doesnt matter what the gun is, if your lackadaisical or become complaisant in your handling, youre apt to have issues.
