I have my STAR Super Model B in mine. Like most people said, it's easier for me to reach into the glove box and grab it as opposed to pulling my primary side arm from the sitting position.
Yes. As a matter of fact the US Government has just placed a large order for a big batch of 1911's for the US Marine Special Forces (search Fox News.) Lucky them! They have been complaining about the current Beretta 92FS' stopping power. Nothing beats a .45 I guess.
