They shouldn't, for aftermarket grips.
But the Springfield Milspec ships (or used to) with two sets of grips: One is wood, with a nice-looking but totally non-authentic "US" in the center, and the other a set of full-checkered black plastic. My take on the OP is that the OEM wood grips don't fit well, and the OEM black plastic grips don't fit at all.
