I did a quick search and didn't see anything. Does anyone know if there was any functional reason that Sig changed the width of the slide on the P238? I vaguely recall reading it was because the HD version had a thicker slide and they wanted the tools universal, holsters and what not as well. But I can't be sure that that was it. Anyone know?

I ask because I've got an opportunity to pick up an earlier model with the thinner slide for a reasonable price.
