Narrative:
During our visual approach; we were configuring the aircraft for landing on runway xxr. Upon gear deployment; we got a left main gear disagreement and the left main gear icon was red. I had slowed the aircraft previously to 200 KTS and extended the flaps to 20 degrees then; prior to intercepting the GS on the marker; I slowed to 180 KTS and called for the gear down. The nose and right main gear came down and locked; but the left main gear remained indicating up. We were at 2500 ft MSL now on the GS and I executed a go around. ATC gave us a climb to 3000 ft MSL and a heading of 330 degrees. I executed the climb out at 200 KTS. Once we were stabilized at 3000 ft MSL; I asked the first officer to get the QRH and run the checklist. As he was beginning the QRH; we heard a thump and then the left main gear icon went green. We now had all 3 gear icons green. We were vectored back to visual for runway xxl this time and made a safe landing.

Narrative: DURING OUR VISUAL APCH; WE WERE CONFIGURING THE ACFT FOR LNDG ON RWY XXR. UPON GEAR DEPLOYMENT; WE GOT A L MAIN GEAR DISAGREEMENT AND THE L MAIN GEAR ICON WAS RED. I HAD SLOWED THE ACFT PREVIOUSLY TO 200 KTS AND EXTENDED THE FLAPS TO 20 DEGS THEN; PRIOR TO INTERCEPTING THE GS ON THE MARKER; I SLOWED TO 180 KTS AND CALLED FOR THE GEAR DOWN. THE NOSE AND R MAIN GEAR CAME DOWN AND LOCKED; BUT THE L MAIN GEAR REMAINED INDICATING UP. WE WERE AT 2500 FT MSL NOW ON THE GS AND I EXECUTED A GAR. ATC GAVE US A CLB TO 3000 FT MSL AND A HDG OF 330 DEGS. I EXECUTED THE CLBOUT AT 200 KTS. ONCE WE WERE STABILIZED AT 3000 FT MSL; I ASKED THE FO TO GET THE QRH AND RUN THE CHKLIST. AS HE WAS BEGINNING THE QRH; WE HEARD A THUMP AND THEN THE L MAIN GEAR ICON WENT GREEN. WE NOW HAD ALL 3 GEAR ICONS GREEN. WE WERE VECTORED BACK TO VISUAL FOR RWY XXL THIS TIME AND MADE A SAFE LNDG.
