Layout is important, as John has said.  I'd suggest a very short source lead soldered directly to the ground plane,
keep the drain lead well separated from the other two (Allison suggests clipping the drain lead off and soldering to the tab),
and try adding a 10 ohm resistor in series with the gate.
