Heck replace that deact with a Deepfire and throw some Taginns their way haha. Im thinking of doing a post-apo loadout myself, using some combination of my DP-28, A&K M1892, Umarex Peacekeeper, SMERSH, and probably a cobbled together or distressed launcher of some sort.
Ill admit - your loadout there is more reminiscent of Division-style post-apo than like Fallout or end of the world post-apo. Still works though.
