I carry my 1911 in a galco iwb holster and I think your single action army would hide nicely in one also. Go to a store where you can try different holsters just like you would try different hand guns and see what you like. I use several different holsters for different times of year, IWB for summer and a don hume OWB for winter. Good luck and be safe.
