Im not sure if you can find a full size ankle holster. I bought a ankle holster for my subcompact Glock and it sucked wearing it. Its a lot of weight on your ankle which screws up your walking. It can print through your jeans, and it is hard to draw from (you need both hands to pull your jeans over the gun, which would be near impossible for a large gun). My ankle holster also beat up my ankle and does not stay in place. I would suggest carrying your full size the way I do, shoulder holster or IWB.
