The question on a 10 round pistol, 9mm pistol, being enough for home defense. As you are in possession of that pistol right now, question answered. Me, personally, carry a Glock 19, 15 round magazine, plus one in the pipe, 16 rounds? Why you say? Why not I say. But as you are not in the market for an other pistol, what to do to maximize your firearm. If you are dressed, be armed. Carry a cartridge that is known to have been proved to work in actual shootings. Now, hitting good spots, is more important than, within reason, what you shoot that spot with. Just like Real Estate, Location/Location/Location. Every extra $10.00 you can collect, a box of cheap target 9mm. Because shooting from your carry holster, dressed the way you dress really. So, even though the chance of using a carried Pistol, in defense, is remote, as we all know, it does and could happen. So when you, with adrenalin courses through your veins, you do not hook up your cover in your draw!
