I believe I would pass, also. Drew pointed out a simply wonderful fact that few peoples dream guns remain so, forever. Mine have evolved, over the years, and guns I believed were the dream came and went. I still quest, but, I'm a bit jaded these days, as well.
.019 wall isn't a lot of material, just from an impact resistant point of view, much less a progressive powder point of view.
Good luck, at any rate, and do keep us posted on what you do. There will be other dream guns, if that makes you feel any better.

Best,
Ted
