From a legal aspect, many states prohibit the transport of a loaded rifle or shotgun in a vehicle. Such laws usually don't apply to "handguns" such as arm brace equiped AR15 pistol variants. This along with compact storage constitutes a major advantage for arm brace equiped AR15 pistols.
Both Mossberg and Remington have models with detachable magazines, which would allow fast loading and be legally compliant
