While the heavier bullets do to better at long range they also increase terminal performance at short range. There are a lot of people who pick a load without adequately researching the ammo they trust their life on. BARREL LENGTH plays a role in this as well. The Barnes all copper TSX bullets are great projectiles the 55 gr TSX is optimal for LE use--ex. As far as the idea that pistol bullets will inherently penetrate less than rifle cartridges, take a look at this graph comparing common weapons one might employ in the role of self-defense: Too low of a velocity will cause the bullet not to expand and can lead to overpenetration.
