I've got the same holster and the same problem. I put a pretty good scratch in one of my walls trying to squeeze past my wife (carrying laundry) in the hallway. I turned sideways with my back against the wall to get passed and gouged the wall with that back loop. I may look at altering it put so far I've got no answers and am hoping somebody comes up with a good clean idea.
all men are justified in defending themselves,their friends,and property,and the government,from the unlawful assaults and encroachments of all persons in times of exigency,where immediate appeal cannot be made to the laws,and relief afforded. D&C 134
