4.40 (180-man) Was this a good time to push?

[ArtMonkRules]

Final 2 tables (In the money, 16 players remain (9th-18th all pays $8.64)). I'm sitting at the low end of the chip count with 6970, and I'm at MP1 with the blinds at 400-800. I decide to go all in with QT because I'm feeling the pressure of the blinds, and don't want to get too far behind. Was this too hasty?
