My vote is for the High Power.
Since you don't have a 1911 on the list it seems a natural choice for someone looking for a fun to shoot range gun. Sig makes a fine pistol, some would argue quality has been spotty lately, but the longer barrel of Mr. Browning's design lends itself to accuracy in a proven weapon.
Revolvers lend themselves well to shooters with a purpose. Whether hunting or bullseye shooting, you can't go wrong. If high volume fun is your general goal, you may find yourself trading for an autoloader then wondering where your accuracy went.
I'm sure someone will argue that autos are more accurate and more reliable and their brand never jams but the Glock poster above can't even spell quality. (sorry for the jab, it is spelled incorrectly).
Back to my choice, Cabelas had a special last week which may still be running on FN High Powers NIB for $550. They were produced in 1998 and are the last of the Belgium made pistol you will find. A true steal, I would have bought myself one but was feeling greedy as I was shopping for the wife's first pistol. (would have made a great choice but I would have been sick with jealousy).
Good luck with your decision.
