Is there anyone that has a v-tac (v-tec???)? I have never been a fan of the M&P pistols, mainly because I havent handled many. However, today I held one and my hand immediately got an erection!! Can someone with experience with this firearm please tell me about it? What is the difference besides color and sights between this model and the regular M&P? I have a feeling I may have to get me one in the very near future, however, if the differences are just the color and the sights, I will save my money and find a used M&P40.
