So I finally got my M203. The barrel at least; the receiver should be at my FFL early next week. I have a 9" barrel, but taking a look at it it looks like it may be possible to cut it a little bit. The top of the barrel has a groove that is used to aling in the the receiver but I'm not sure it needs the whole thing. I'll post a picture later today.

In any case, I know someone that has the 9" in stock. It may be more beneficial to just buy the 9 and sell the 12. I'll PM you the link.
