HL2RP Attachment models selected by gender

Greetings,
does anyone know how I would go about making ITEM.attachmentModel selected by gender?
I have a male and female model attachment model, and instead of making two different items, I believe there must be a way to make it figure out what gender you are and base the ITEM.attachmentModel line off of that.

I've tried this so far, doesn't seem to work - no errors or anything, just not selecting the right model:

Code:

local ITEM = Clockwork.item:New();
ITEM.name = "Test attachment";
ITEM.cost = 0;
ITEM.model = "models/bandmodelm.mdl";
ITEM.weight = 0;
ITEM.category = "Bands";
ITEM.uniqueID = "bandm";
ITEM.business = false;
ITEM.examineOveride = true;
ITEM.description = "A band description.";
ITEM.isAttachment = true;
ITEM.attachmentModel = "models/bandmodelm.mdl";
ITEM.attachmentBone = "ValveBiped.Bip01_R_UpperArm";
ITEM.attachmentOffsetAngles = Angle(male offset angle goes here);
ITEM.attachmentOffsetVector = Vector(male offset vector goes here);

-- Called when the attachment offset info should be adjusted.
function ITEM:AdjustAttachmentOffsetInfo(player, entity, info)
    if (player:GetGender() == GENDER_FEMALE) then
        info.offsetAngle = Angle(342, 82.42, 146.84);
        info.offsetVector = Vector(0.663, -0.414, 7.18);
    end;
end;

-- Called when the attachment model info should be adjusted.
function ITEM:AdjustAttachmentModel(player, entity, info)
    if (player:GetGender() == GENDER_FEMALE) then
        info.attachmentModel = "models/bandmodelf.mdl";
    end;
end;

 

Untested, and I think you kind of need a hacky workaround to do this.

Create two separate items and script it to decline the other gender.
