In a Poincare-covariant vector-boson-exchange theory, the pion possesses components of pseudovector origin, which materially influence its observable properties. For a range of such quantities, we explore the consequences of a momentum-independent interaction, regularized in a symmetry-preserving manner. The contact interaction, while capable of describing pion static properties, produces a form factor whose evolution for Q(2) > 0.17 GeV2 disagrees markedly with experiment and whose asymptotic power-law behavior conflicts strongly with perturbative QCD.
