I am wondering if there are any companies out there that offer a .22LR conversion for the M&P45c. That is one MAJOR advantage I think Glock has over the rest of the polymer market and since I really like this gun and enjoy shooting it, I think it would be nice to get a conversion unit so I can afford to practice with it like I want to. I haven't been able to find any information on this and so I figured I would ask you guys and see if I'm missing something. Thanks for your help.
