Flight Crew Executed Go Around / Missed Approach
Aircraft
On approach as flaps 5 were selected; the flap gauge did not move past the 1 position with a slight asymmetry. A go-around was initiated and the flap lever was set to position 1. The QRH was referenced and a flaps 1 approach was accomplished as per the 'Flaps; Trailing Edge: Asymmetrical' with the flap lever in the 1 detent. The landing data was recalculated and stopping margin and brake cooling were not a factor. Approach and landing were uneventful. I felt a bit rushed to accomplish the checklist and get the aircraft on the ground. Fuel was 5.7 when the go-around was initiated. ATC was keeping us busy with frequency and altitude changes. There was enough fuel to take more time to analyze the situation.
B737-300 Captain reported asymmetrical trailing edge flaps on approach. Go-around was executed; procedures run; and a normal landing ensued.
