AS another carrying Jew, I'll put in my two cents:
Rule #1, be armed. To that end I start with my .32 Beretta Tomcat, almost undectable and concealable anywhere.
Moving up, I own a marverlous Walther p88 Compact, which shoots straighter than straight, has preban 14+1 9mm load, and ergonomically is awsome in my hand.
Next, I have gone Israeli, and purchased a Baby Eagle(or UZI) 40 S&W compact, night sight polymer lightweight, cheap good shoorin' semi-auto.It was 329 plus change at CDNN.
Rest of the Home /Life defense Remington pump home defense model, AR 15, Galil Hadar .308, and plenty of Ammo. Good luck.
