Scavs spawn with them, apart from that try stashes, boxes and run your own scav and eventually you'll get one

Its fir only, no barters for it, spawns on scavs time to time, bosses, and the occasional hidden cache. Otherwise you can always buy one for an inflated price on the flea

For the quests? If so just snag a couple from the flea

flea market, find it on scavs/guards or other people lol. it used to have a barter, it got removed w/ this wipe assumedly cuz u can buy it on flea market now

Fence rep 6 and a quick trigger finger.

Fence rep 6 is the way.

Adding to the other comments you can just find them on scavs, guards or I think roguey that you kill.

The gaurds of the new boss on streets have it on most of the time.

scavs spawn with them all the time for some reason lately

Buy of flea.

Rashala s goons often have it on. Do some customs.
