Don’t get me wrong, I love my all steel guns. But if you suffer from noassatall you need polymer guns to help keep your pants up and keep some dignity. 
I can appreciate a firearm made of steel, at the range, or in my safe, but all of the ones I have ever carried on me had a fair amount of either aluminum and/or plastic in them.
Even with my P-07 rig I had to work over time to get the right combination of belt and holster to hold it up correctly and prevent the "pants on the ground" effect.
With a properly adjusted nylon Kore gun belt, and a good Kydex IWB holster with a griphook, modwing, and a piece of Talon grip material opposite the belt to provide friction against my undershirt, my pants are going nowhere.
