Confusion on nishas controls

So can someone tell me how nishas dual wielding pistol skill works. Is it like salvador where left mouse shoots left gun and right mouse shoots right gun, because I loved that but someone told me that nisha is way different which kinda bums me out cause I loved sal. Anyways… What’s the mechanics for nisha?

Left Mouse button shoots both guns. Randomly for Jakobs, one after the other for other pistols. Holding right mouse gives you ADS with the right (main) pistol only.

Is there a mod or way to convert it to play like salvador
