I found this product, for cleaning the Glock 9mm and 40 S&W magazines, on another gun web site and ordered it. I recently received my GTUL in the mail. It arrived earlier than expected. After following the instructions, I found it to be very easy to remove the plate and with the brush clean the magazine. It was so simple I could not believe that someone has not invented this before. Now instead of waiting for my magazines to get nasty I will clean them more often. The only question I would have is when will they be coming out with a GTUL for the other calibers? I recommend the GTUL to anyone who wants to clean their magazines without the hassle. The web site is wwwmygtul.com. Go there for a video.
