I sure ain't pouring anything through a 2mm hole so it is injection molded. The material goes into a cylinder and is forcibly injected into the mold cavity. Semantics aside, I wanted the magazine to look as close to the real thing as possible. The color matching was not easy but because I am not using the same material as Hk, the color match differs from light source to light source, but you are right, it is a very good match. I've been using these magazines for awhile now without any problems. I've sold a few as well over the past couple months and have not had anyone complain about function. Also, any loaded magazine that is dropped on its floor plate could crack, even Hk. Stop with the flattery, you're making me blush.
