Lancair IVP pilot reported landing with the left main gear up. Reportedly; the pilot repeatedly tried to manually put the gear down without success before deciding to land the aircraft.

Narrative

I landed Aircraft X into the ZZZ International Airport without the left main gear. About an hour and a half before I landed I was shooting an ILS approach into [Runway] XXR and when I put the gear handle down there were only two green gear indication lights. At this point it seemed to me that the nose strut and right main were down in their lock position. I then contacted the tower and told them that I didn't think my left main gear was down. Next; I leveled off and did a low approach over the runway in order for the tower to see if the left main was in the down or up position. Tower then stated that the left main was up so at this point I knew it wasn't an indication issue. Moving forward; I followed the checklist for the emergency gear extension and performed over ten laps in the pattern (exact number is uncertain). Each time that I did a low approach over the runway; I verified with the tower to see if the gear was up or down. The emergency gear handle was pumped as stated on the checklist until 'stiff'; at this time I was physically unable to pump the handle more due to the amount of pressure that was built up from pumping it. After performing the emergency gear extension steps the left main gear would still not come down. Being the Pilot in Command I then decided to land the airplane without the left main gear and the two souls on board happily walked away.
