How about a build...and the gimmick is you use.... [i]gun[/i]

I like energy weapons. You can (usuallt) get a Recharger Pistol not far from Goodsprings. Pick up a Laser Rifle as as soon as you can, mod the ever-living Jannolor out of it, and that’ll get you through most things. If you have the Gun Runner’s Arsenal, there’s a really good gun you can get in Novac. If you have Old World Blues, the LAER is my favorite weapon ever.

Put everything into Strength and Endurance. Disregard Intelligence. Use fist to smash good.
