I have never used a shoulder holster much..but I have decided that because I am seated most of the time behind the wheel of a truck...that a shulder holster or crossdraw holster would be better than the standard strong side carry...I tried a cross draw and really like it but when I have to leave my truck it is hard to conceal an untucked tee prints like crazy and even an unbottoned shirt over a tee still show pretty bad...I am still open to suggestions on the cross draw but I have also bought a used leather Goodrich and Gould (I believe that is is it) vertical shoulder holster for my browning Hi Power...it has a leather strap that holds the holster under my off side arm and an elastic strap that goes around my right shoulder...it also has a strap to attach the bottom of the holster to my belt...what is the best way to set this holster up...how loose should the elastic strap be and how lower should the holster hang below the arm...should the holster be pulled to the back or sloser to the front...is there a better brand out there if so supply a link please...an help with this will be greatly appreciated...like I said I have never tried a should rig before...remember I will take advice on a cross draw also....thanks guys
