According to Gun Holsters and Gear, Smith & Wesson have given into popular demand. They will be making the M&P shield without the thumb safety. Apparently an all too eager dealer mistakenly leaked this promotional image a little prematurely; which led to discussions of its authenticity. However Gun Holsters and Gear’s sources have confirmed that it is real.
No details of when they will be available. MSRP will remain the same. I was honestly surprised it took S&W this long to make one when considering the multitude of variations that the M&P pistols come in.
