So I am playing with the Hardcore 22 V2 mod which makes enemies a lot more deadly but removes the egregious spongyness of very hard mode in exchange.

This gun just has it all, quick fire shotgun blasts for cqb, long range still fairly quick lovetaps to the head for when a ton of enemies are rushing you at once and of course a charged mode to punch through walls, just beautiful with stalker optics (I also banned myself from using the middle click highlight because its OP as hell)
