An improved perforation gun includes an outer gun barrel, which is used in conjunction with an inner movable charge carrier or an inner movable sleeve to trap virtually all of the debris created by the firing of the perforation gun. The charge carrier has a plurality of explosive charges initially aligned with complementary, pre-existing holes in the wall of the charge carrier, which are initially aligned with complementary, pre-existing scalloped sections of the outer gun barrel.
