I used iron striker+ (it's a hammer) and full blangonga armor. Bring 10 potions, 10 mega potions, 10 honeys, 10 herbs and 10 blue mushrooms. Bring hot drinks and shock traps and tranquilizer bombs to capture him.

That's how I've beaten him for the first time. Tigrex really is a tough monster. Just wait, later you'll have to hunt two high rank ones in one quest, then even two G-rank ones. Mwa-ha-ha.
