The thought doesn't bother me as long as I am standing up. Like I said I have been carrying my 38 revolver (2") like that for years. Although I feel safer because it is a harder trigger pull and the hammer has to strike the bullet. With the semi, it is a striker pin.
Also, with the M&P 40C I feel like there is more gun pushing upward while sitting or bending over to pick something up. Making me think it is easier to get pushed out of the holster. Maybe it is more a mental thing than reality.
No doubt that if I am just going out for a walk it is a lot easier to stick the appendix holster in and go.
I don't know. Now I am thinking I should sell this one (even though it is only 3 weeks old) and go for one with a safety????? ugggh
