No, they won't fit the 92FS compact model. However, wait for Shipwreck to respond as he is the man to answer your question. He owns or has owned every 92 model out there and the 92FS compact is on his wheel of Beretta's. I beleive the 92FS compact has a shorter grip than the Centurion and the full size models listed for the grips on Beretta's website.
You may want to check out these grips from cdnn however.
