I don't believe pistol-caliber carbines were designed to be 100 yd guns. For the most part, they were designed to provide more accurate, user-friendly, higher capacity shooting than their equivalent caliber handguns at short ranges. Most can probably provide moderate accuracy at 100 yds, but we're talking about cartridges that are low-powered compared to long gun calibers. A 7.62X39 has about 1200 ft-lb energy at 100 yds, and 9 mm has about 250. So if you're simply talking about punching holes in paper, the Storm might do as well as an AK, but the terminal ballistics aren't comparable.
