You made that up. You need to re-read the manga. LMAO you can't be serious ahdhothdfidgfvuf......
G2 was ready right before he clashed with Chinjao. He used G2 to kick Sai out the ring and used it constantly against Chinjao. Chinjao shook off the G2 Hawk Rifle without a scratch while Luffy was the one with scratches.

It took G3 to take out an arrogant Chinjao who tried matching the blow instead of dodging. Again, Luffy was using G2 the entire fight. Stop downplaying characters because they are not Zoro and you hate Sanji(if you can claim people are Zoro haters because they disagree with you, I can do the same).
