Smith & Wesson M&P .40 Training Guns

[megasaurus]

My agency recently changed to the M&P .40. The problem is that there aren't any training guns made for it. The M&P is a double action only so we would need a training gun that you could use single action and still get the gun to click for training purposes. Does anyone know if such a training gun is made and by whom? It could be an airsoft type weapon or something along those lines as well. Thanks!!
