Narrative:

On approach to runway xxc at ZZZ; we experienced a landing gear malfunction. On GS about 4 miles from the FAF; I requested the gear down to start the speed reduction from 210 kts to 180 kts. When the gear handle was placed in the down position; nothing happened. Three red lights appeared; but no other warnings. We cycled the gear handle with the same result. A soft go-around was initiated and [advised ATC]. Fuel on board was 5.8. Side of body was 111.contact with dispatch was established with a 'call me mayday' request. [Maintenance control] assistance was requested to help with troubleshooting. Of note; communication was difficult as it was hard to hear them on the frequency. We switched radios to try to remedy. No help. I flew the plane and handled ATC. Captain coordinated with dispatch; [maintenance control]; and the cabin crew and made the appropriate pas to the passengers.once we exhausted all options for an in flight remedy; the appropriate checklists were completed and a gear down-and-locked indication was achieved after the manual gear extend procedure was accomplished. Arff (airport rescue and firefighting) equipment was requested; and dispatch contacted ZZZ operations facilitating the anticipated tow-in to gate xx upon landing as our nose-wheel steering was rendered inoperative after the manual gear extension.ATC assigned us runway xxr and after landing; the aircraft was brought to a stop on the centerline. The arff inspected the aircraft for any hydraulic leaks and we communicated via a dedicated control frequency. The APU was started; and engines were shut down. Tow-in checklist was completed; the gear pins were installed and we were towed to the gate. Block in fuel was 3.5.
