Hate to repeat stuff that's been said 3 posts in, but the FDE grips aren't out for the 45s yet. They may have a model number out and a few pictures on their site, but it doesn't mean they've been released yet. The stainless/black and black/black USGs are out (no model number on the FN website).
Give FN a call/email, they may be able to tell you when it will be released or if a dealer could order you one right now.
