Non-lethal bullets work effectively in most situations.

Regular bullets can be stopped by reinforced skin or other protective measures. Of course, this was meaningless information against those thugs. Against proper mercenaries, destructive power couldn't be guaranteed.

Unless it's an extreme case like Brown Hood, most mercenaries or gang members wear implants. Non-lethal bullets work on them.

They're much more expensive than regular bullets, but I didn't need to worry about money. I could afford that investment.

Besides, considering how easily people die in this city, I needed to at least check who was killed by my guns.

A stray bullet could kill an important character. Rick, who stands before me now, is also someone who could die from a single bullet.
