That still seems too tight... Air needs to be able to escape from the jar. When we say finger tight, I think that we are meaning one finger and one thumb, lightly applied until the first hint of resistance is felt, not a palm, and not a thumb and 4 fingers, not a jar gripper.... The vacuum will hold the lid on the jar after it comes out of the canner.
