I own one Glock, a G30sf. It is a great shooting pistol and fits my hand well. I also have a S&W 4586 and a Para Ordnance TAC-Four as well as a Kimber. The Glock is the lightest of all, but also the fattest of all by a good quarter inch. I wonder why Glocks are so thick! I am talking about the slide/reciever part of the gun, not the double stack mag well. Can't see why a Glock needs a thicker steel slide than a 4586.
It makes it less comfortable to conceal than the others, in spite of its low weight.
My Glock has the Smyrna, Ga. address on it as well as the verbage "Made in Austria".
