I also prefer the safety and don't consider myself "gun dumb". The bottom line is that I cut my teeth 30 plus years ago on single action guns like the hi-power. I am trained to sweep the safety off. I also am of the mind that the trigger safety is not sufficient as it is too easily defeated. I believe that this position has been proven out by the number of AD/ND's of the Glock platform.

One of the reasons I moved to the M&P platform was because of the availability of the thumb safety. The ergonomics are as close to the hi-power that I have found in a current design. The Shield with a thumb safety is the best concealed carry platform available today.

While I appreciate that some feel they don't need a thumb safety, I feel strongly that they are incorrect. I just hope that they never find out how incorrect they are in their misguided confidence in an inadequate trigger safety.
