Luffy's actions in chapter 911 was interesting. What is the possibility that Luffy used future sight here? This didn't look like a normal use of observation haki. Looked like he knew the bullet was coming and acted accordingly. Normally he would just dodge the bullet. Also the panels looked much emphasized for fodder cleaning. Did Oda tried to showcase Luffy's upgrades here after the Katakuri battle? Also it's interesting that Luffy never even let them fired. Almost like after getting shot by Flambe in the mirror world he realized it's better not to let them shoot in the first place. Otherwise why would he even care. He tanks bullets.
