For me this is the best holster.... I can dress up, dress down, set at my desk or set in my kayak, roll around on the ground working on my truck honestly... I have completed a lot of activities with no issues. Plus...Nobody knows I am carrying a concealed weapon. (Glock 43)
I carry my m&p shield appendix in a fusion holster and love i . Have tried multiple holsters and this is the most comfortable. Got it at ccgofalabama.com
