Hello, I'm new to CC'ing and I just picked up my M&P 9c. I've pretty much determined that my body type does not comfortably allow IWB carry from trying a few of my friend's holsters. I found a nice desantis holster on smith and wesson's website and it's available with and without a thumb break. I know it seems like it would be a lot more secure in the holster with the thumb break (i.e. sitting, driving, etc.), but I'm afraid it would be a huge hassle in a needed situation. Just looking for commentary from people that carry either way.
Here is a link to the thumb break holster I was looking at. The non-thumb break is identical, obviously w/o the break.
