All of my shoulder holsters are vertical and have a loop to fasten to my belt but I usually don't fasten them. One reason is I am lazy and don't do anyhing I don't have too. The other reason for not fasting to my belt is if my jacket is not fastened and I lean to the left the holster swings out also and stays covered. If it is fastened to my belt when the jacket opens up the holster stays close to my side and is easy to spot. But I want the belt loop so I can hold it close if I want too. Larry
