This results in a very weakened stock that's more susceptible to breaking at that point.
If memory serves me correctly, the PT&G and Accurate-Mag AICS bottom metals were designed to be a direct replacement for the standard Savage bottom metal for the 3-4 round mags. Haven't used either myself so can't say with absolute certainty - just going off what I've seen others post here.
