I've received my today, after long struggle with CanadaPost (they have delivered it to the wrong address and considered it "delivered", of course! It is mostly luck that I've finally got it).
Extremely happy with it, can't wait to shoot the shotgun.
I own JIC II (Just In Case 2) variant of Mossberg 500 which comes with pistol grip. It is a takedown shotgun with a 18.5" barrel and beautiful matte finish and I love it. But the pistol grip it comes with is pain to use - I mean, it's really painful to shoot buckshot and slugs, it kicks your hand hard.
At some moment I decided to buy a shoulder stock, but it is annoying as hell to attach and detach it, and it makes the shotgun look and feel different. In addition it makes it impossible to use as a quick takedown shotgun, and it doesn't fit in case.
Finally, I decided to buy a Raptor grip, because I've read some good reviews of it.
The grip is simply great. Ergonomics is perfect, the look is 100% badass. It feels so good in hand that I don't want to return the shotgun back to the case. There is one bad point about it: moulding is not 100% perfect, so in few places it is rough or sharp, but it took maybe 5 or 10 minutes to remove all these spots with a small knife (it doesn't affect the look at all).
If anybody wants photos, I can take some, but generally it looks exactly like on pictures from the Net. The only thing photos cannot really express is a lovely texture of the grip surface and rock solid build.
