I have always had a fascination for WWII, military and period police gear, so my day to day dress usually has some accessory or equipment that is inspired by the above. I normally carry a concealed pistol/revolver, in a holster(very rarely mexican carry
).I have several holsters, some that I have made myself, some I designed and had my "leather man" stitch for me, and some were bought. The first 3 below are pics of a "pistol bag" that I designed, that can be worn on the belt, or by a shoulder strap or on a Sam Browne belt overtly, as it looks more like a binocular case or a camera bag (my grandad's binocular case is next to it) 
For times that I dress more "modernly"
I had this bag (below)modified with a velcro flap to retain my pistol, as above it can be worn overtly on the belt or shoulder strap and does not look like I am carrying a pistol. 
Below are pics of some of the other holsters, on the left is a commercial police holster(India) the middle one I designed for more "sweaty" climes, I can use this concealed or overt, and the last one I bought in the USA.
Regards,
Anand
