If wanting to carry a Glock 27 as a back up duty weapon and off duty concealed carry, What are the holsters of choice? I realize being creative for the on duty BUG, like a inside vest pocket, may be the best choice. If you have some ideas there, great. For off duty I think an IWB would be the choice. Please limit suggestions to experience with at least this style weapon. I would appreciate even more the 1st hand experience with LEO using 27s. The choice of back-up for now is already made so don't get into the revolver auto or other options debate, please. I am not a LEO but the info is for one.
