A subcompact 9mm or a .38 Special would do much better.
A surprising amount of people are not put off by a handgun pointed at them. Also it takes training to fire a handgun accurately in a stress situation like that. No, I go for a Mossberg 500 12 gauge pump, barrel shortened to about 20 inches (which makes it an excellent quail gun also), buttstock shortened slightly, loaded with #4 buckshot. I've never yet heard of anyone hearing one of those pumping a round into the chamber and not get put off. Bed holder.
No, a semi-auto would not be better, among other issues, too much possibility of pulling the trigger more than once. And if not familiar with this firearm some training/teaching would be appropriate. It is also very important not to shoot unless an actual intruder is identified - a number of family members get killed this way.
Aguila makes mini shotgun shells, so you can load more. However, as is they do not feed well, so a about a $20 gadget must be bought and used to feed reliably - don't recall the name at the moment, but thinking Amazon carries them, don't know if WallyWorld does or not.
Got it - OPSol Mini-Clip.

Some days, the supply of available curse words is insufficient to meet my demands.
Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
