Narrative:

Inside the marker on a visual; I called for flaps 25 before the gear was fully down. Got gear warning. First officer tried to quickly go back to flaps 20. Flaps stuck just shy of flaps 25. I determined that we had a safe aircraft and intended to land with the flaps in this configuration. I added 20 KTS to the final approach to increase the safety margin and to insure clearance of the tail. Landing was uneventful. After taxing clear we ran the QRH checklist. When finished; we returned the alternate flap selector to the normal configuration and the flaps operated normally. I informed maintenance that we self-induced the non-normal and that the aircraft now operated normally in all regards. In retrospect; I should have given more consideration to executing a go-around and running the QRH prior to landing. Preventive measure I would remind myself not to turn a non-time critical non-normal into a time critical non-normal.
