I myselfprefer a1911 with a few tweaks.
My cousin has 2 walthers. Great shooters.
Onehe abuses.One he uses as a paper weight on his headboard.
I am not big on S+W or Glocks. Just me and the feel.
I like the all steel Baby Eagle. It just feels right to me. Shoots good too.
Beretta 92 carries well.
A few kinfolk of mine have Springfield XDs. GREAT PISTOLS!!!I would look no further if I was in the market for a new sidearm.
A good used Colt Combat Commander is hard to beat if you can find one.

But to stay on track...Out of your choices I sayWalther.

I relate the .45ACP to a 1960's Big Block.
Theremay bebetter choices but the "shock" factor is unrivaled.
