personally we can go around options 2 and 3, allow SMG's to be bought from rebel and lower ranking officers in PD, these will run for around 10-15k
Allow Crafters to make class 3's and make higher ranking Officers (cpl/sgt+) & Spec-Ops able to run class 3's in code amber and major crimes, with CERT able to run class 3's whilst at DOC void the restrictions mentioned earlier, this will reduce the influx of class 3's into the market from just guns being bought from the store, and from police getting robbed
Allow Class 3's from civs to be used anywhere
