  It is shown in the tetrad representation that there are Reissner--Nordstr\"om
solutions with a finite action and total inertial mass equal to the
gravitational mass of the considered system. These solutions describe systems
of electromagnetic and gravitational fields without any admixture of massive
point-charges. The stress tensor for this solutions is shown to be identically
zero. This means that there is no need in additional nonelectromagnetic
surface-tension, existing in the Lorentz electron model, preventing the system
disintegration. The hypothesis that gravitation can play a crucial role in the
structure of elementary particles is discussed.
