It turns out that the .44 Magnum Bullet is indeed much more powerful than the 9mm Parabellum Bullet, but there's definitely something wrong with this guy—getting hit by 12 bullets and still alive and standing, what kind of person is he?
Jimmy didn't have time to change bullets, so he held the gun with both hands and exchanged two punches with the man, then lifted his leg to kick the middle-aged man, stepping back two steps himself.
Being shot definitely had an effect on the middle-aged man; his bodily control had significantly decreased during the exchange with Jimmy, far less agile than when he was fighting both Rodney and the Priest earlier. Unexpectedly, he got kicked by Jimmy, his body swayed, and Rodney and the others rushed over at this moment.
