The folks from B&T AG formerly known as Brügger & Thomet AG of Switzerland created this super fast magazine loader for the MP9 and HK MP5 which shoots the 9mm rounds, but before you get it for your Glocks, read this first. A loader like this WILL NOT work with a single-position-feed magazine like a Glock (or pretty much any pistol) magazine. It will ONLY work with a double-position-feed magazine like most SMGs and rifles use. See the video here on how fast you can reload your magazine here.
