MP44 pouches are not smaller than MP40 pouches. In fact, they are bigger. And with magazines in them, they are huge. They even required an extra strap to wrap around the back to help keep them in place on the waist. In addition, Mp44 clips are banana clips, meaning they are curved, so the pouches are also curved and not at all squared off like the smaller MP40 pouches. They may look square in pictures with no mags in them, but they are not.
