I just posted in the general handgun forum a request for information to convert my post ban 9MM 10 round USP magazines to the 15 round configuration as origionally intended by HK. I know that there is a kind of a block inside the magazine body but I don't have a clue as the correct way to do the conversion correctly. As I indicated I live in Florida and there are no magazine capacity restrictions to make this conversion illegal. The conversion would be considerably cheaper then having to purchase new 15 round magazines. Anyone out there who can help me with my project?? If not anyone know where I can buy 15 round magazines?
Thanks for your help, sneaky pete

I dont know what a 9mm mag looks like, but I do know that the .357sig mag has 2 pieces of the baseplate that hook into the metal part of the mag to keep the baseplate secured to the floor plate. I dont think its possable to convert it, since you would have to change the way the baseplate is secured to the mag walls. Anyhow, i dont plan to try, as i would only get 2 extra rounds anyways. Wish someone made +2 extensions for the darn thing like they do for glocks. Hmmm.........theres an invention.
