not yet but I'm thinking about making a temporary fix for mine. I don't have any plastic fab skills so I'm going to use rubber. I don't mind it though, may not mess with it. I'm used to using the short mag.
Oh and the full size mags hold 18. Before you call me an idiot, go try it (I had to eat crow twice over this already). You'll have to set the mag on something to be able to get it in there but it works. I've only ran 2 mags through mine like that but it seems to be fine.
