I am thinking about picking up a Walther PPQ. The only other handgun I ever had was a Beretta 92 with a thumb safety. I feel a little strange getting a gun without a thumb safety considering every rifle or shotgun I have ever had always had a safety and I was taught to use it religiously. Am I overthinking this? How do you feel about it? I know about the other safety aspects of the gun, however, there was some comfort with the extra thumb safety. Thoughts? I know S&W makes a thumb safety model as does some other manufacturers, ie, FN
