On a serious note it would be nice to see more type of weapons for certain types of ammos.9 mm, needler ammo, 14 mm (22 cal is similar since its used in hunting rifle and its scoped version only) they are used by only one weapon. It would be good if there would be 2 type of weaponry for every ammunition. Maybe a rifle version for all these pistols with same stats.
I though for exact copies same stats just rifle version I think that would take less time then to tweak around with damages for burst attacks and would give chance to have more type of weapons that could use up those ammos.
Mausers... rifle stock... increase range...
