His daily carry is a Smith & Wesson M&P 2.0 chambered in 9mm. I noticed he has the model with an external thumb safety. What do you guys think of external versus internal safety mechanisms? Do you prefer having a thumb safety or no external safety?
And if you do have a thumb safety do you use it on your holstered gun and have you trained to speed the time it takes you to draw and flip the safety off before firing?
