And you're pretty accurate on the "not necessarily for cc" comment. Would probably feel like an anchor on your side if you're not used to carrying.
I haven't seen interchangeable grips on the Glock, although some use abrasive tape for a better grip, rather than just the plastic. The M&P comes with Sm, Med and Large- very easy to change, too.
