My earlier interest in an M&P CORE had dissipated after reading numerous posts and internet threads about the accuracy of the M&P. It seemed counter intuitive to buy a gun for improved accuracy, with the accuracy problems it seemed to have. I looked at other options and came to the conclusion that, cost wise, S&W had everyone else beat. Also the .40 cal seemed to not have the same accuracy issues as the 9mm. I did an about face and purchase the non ported M&P .40 cal CORE. When Apex comes out with their 40 to 9mm conversion barrel, I will have both platforms at a great price. The 40 cal cost me $632 with no extras fees. I did cheap out with a Burris Fastfire ll for $178 however. So far no buyers remorse.
