Not "gun dumb". I have been an active handgun shooter for almost 30 years now and a competition shooter for about 10 years. I like the 1911 style thumb safety on the M&P pistol. I use it and it gives me a piece of mind. I do not like the very small thumb safeties on the Ruger SR9 or the M&P Shield. Under stress I would not be able to de activate those little safeties.
