First of all 'over penetration' is largely a myth. The instances of a projectile actually passing through the intended victim and harming an innocent are few and far between. Under penetration and missing the target entirely and hitting a bystander are however real concerns.

The 158 grain JHP(most brands) at 1300 or so fps from a four inch barrel, is the standard in .357 Magnum. The 125, 135 and 180(Nosler-HP and XTP) are good too as is the all copper Barnes.

The 110, excepting the Barnes, is generally considered too light and has poor penetration.

So all in all you friend is incorrect.
