What is the preferred Firearm and Caliber for investors?

[James McGovern]

lately in attending foreclosure auctions I have ran across more than a few hostile individuals. I know I am not alone in belief in our second amendment. On YouTube there seems to be only a few carrying firearms. I support Holton Wise for showing the importance in their videos

When I was a Realtor showing rehabbers every dang abandoned, frozen foreclosure in January (10 degrees colder inside than outside after a good overnight cold-soak), I never knew who or what was inside.

Smith & Wesson .38 Airweight loaded with +P rounds.

NOT a fun gun to shoot.  With the light weight it kicked like an angry, drunken mule.  But I could pocket carry with a neoprene pocket holster and it didn't print at all.

You put 10 rounds through it and you kinda wish you hadn't.  Unless you like throbbing hands.

Very light, very concealable.  Just hope you don't have to shoot it.
