There are three different firearms he talks about, with one being split into two subsets.
Carbine- rifle caliber carbine and pistol caliber carbine
Shotguns are easy to operate, and have a high lethal impact, but they are not as maneuverable as a pistol, and they have limited rounds. It is unrealistic to expect to be able to reload a shotgun quickly if needed for home application.
Handguns are smaller, very maneuverable, and easy to operate, however, they require a higher skill to be accurate, and are harder to master, and hold roughly half the ammunition as carbines.
Carbines, in his opinion, are the best option for home defense, due to the high lethal impact, high round count, and accuracy, however, they are not as maneuverable.
No matter what your decision is, Larry still feels that you need to obtain a good skillset with a handgun, as you may have to rely on it as a fallback. You may need to transition to a handgun at some point while using a carbine or shotgun, so you need to be aware of that and how to effectively use a pistol.
