I think too much of either can negatively impact the other. Shooting a rifle or pistol accurately uses precisely aimed, stationary gun and fine, deliberate trigger control with a surprise break. Shooting a shotgun is pointing with gun moving and quick trigger control at precisely the right instant. For sure, shooting a shotgun destroys my trigger control for shooting a pistol accurately. When shooting both pistol and shotgun in the same range outing, I always shoot the pistol first.
