I carry a Glock G-27 every were I go off duty even fishing. As for all the talk about glocks, The frame is polymer but the slide and barrel is metal the hard-coat they use on the metal parts is real good and will hold up to saltwater (I have a buddy that takes a G-17 diving) The rifling on all glocks is called polygonal rifling, instead of the traditional lands and groves it has hills and valleys. But like someone else said you never take out your weapon unless you are ready mentally to use it, if you draw down on someone thinking its going to scare them and you will not have to use it you are wrong, lots of criminals are not afraid of a gun pointed at them and may even attempt to grab your gun. most important thing you can do is always create distance.
Left is standard rifling and right is polygonal
