Many good stocks, but to find out how to equip weapon and set the max ammo, need a bottle of vodka.
By try and fail, using some your examples, my final variant:

PHP Code:


void PlayerEquip(int client, char[] weap_name)
{
    int type, id, iEnt, iCurWep;
    float vOrigin[3];
    GetClientAbsOrigin(client, vOrigin);
    
    if( weap_name[0] )
    {
        type = L4D2Wep_IdentifyItemByName(weap_name, id);
        if( type == ITEM_MELEE )
        {
            if( !L4D2Wep_IsValidMelee(weap_name) )
                continue;
        }
        
        if( L4D2Wep_IsValidItemAndID(id, type) )
        {
            int slot = L4D2Wep_GetSlotByID(id);
            iEnt = L4D2Wep_SpawnItem(id, type, vOrigin, _, _, false);
            if( iEnt != -1 )
            {
                iCurWep = GetPlayerWeaponSlot(client, slot);
                if( L4D2Wep_IsValidAndEntity(iCurWep) )
                {
                    RemovePlayerItem(client, iCurWep);
                    AcceptEntityInput(iCurWep, "Kill");
                }
                EquipPlayerWeapon(client, iEnt);
                
                if( slot == 0 )
                {
                    RequestFrame(Frame_SetMaxAmmo, GetClientUserId(client));
                }
            }
        }
    }
}

public void Frame_SetMaxAmmo(int UserId)
{
    int client = GetClientOfUserId(UserId);
    if( client && IsClientInGame(client) )
    {
        int ent = GetPlayerWeaponSlot(client, 0);
        int wep_id = L4D2Wep_Identify(ent, IDENTIFY_HOLD);
        int ammoId = L4D2Wep_WepIDToAmmoID(wep_id);
        if( ammoId != AMMOID_NONE )
        {
            L4D2Wep_SetPlayerAmmo(client, L4D2Wep_GetAmmo(ammoId));
        }
    }
} 


Will be good to have it as a stock.
