The scrapped revolvers are fitted with custom barreled suppressors, it's chambered in a custom round of .49 magnum, more powerful then a .44 but very hard to control. The sigs you see here today are mutants who have gone through tough times the female Alicia is always timid and shy but knows her way around a lot of guns. The second mutant is a common mutant you see, this type is always aggressive but also smart to use weapons they have the brains like 40k orkz. The MR6 upgrade is a long barrel for any barrel attachments, and comes with a optical lens that help to zoom in and or go completely into nigh vision.
