I personally will not carry a gun that does not have a manual safety. My M&P .40 is a great gun but it will only see daylight at the range or matches. I bought the M&P .45
with the thumb safety so I could carry it if I chose to. I like the low profile safety on the 24/7 pros. I am considering getting a 24/7 compact to carry because of the manual safety.
