Hand held sabre or jigsaw will do 2", if you have access to one; the blade needs to be on the longer and stiffer side with not too many tpi's for best results; stay outside the line because runout can be an issue, especially if you let it get hot, and work your way through tight bends carefully. Sometimes a strategically drilled hole works wonders in allowing the blade to cut curves tightly. Go slow and it should work fine.
You might have enough for a half-stock rifle and a pistol as well, I think! I assume you are thinking pistols because of size allowance coming home, though.
