Yes it will fit , There could be a bit of extra wiggle room if you try to rock the pistol front to rear but a well fit holster should serve well enough . The no rail SC will also fit a m&p holster if you find a bargain locally and wont to pick up a shorter holster .
My wife had a p250SC and I tried her frame on my p320c
I stayed with the compact frame but did change to a small compact for a bit thinner carry and still works well on the range
