I just purchased this holster yesterday from a local shop and test fit a gun they had in stock the same as mine the xd 40 tactical and it seemed to fit a little sung, may be a little to sung for my liking but he told me that it would break in over time. It is a size 5 and says it fits 4 ½ and 5 barrel large autos, so I was wondering if anyone has one and if the Cordura nylon will be more forgiving over time?
