I bought the railed model. It's going for nearly $1000 more already on
the secondary market. I didn't plan to shoot it and bought it for my
collection. My concern is that there is a warranty so maybe I should
put a few rounds through it to make sure all is well. On the other
hand, it would no longer be an unfired gun - outside of the factory. If
the prices don't move up significantly I will keep it forever so that's
less of an issue.

I guess I'll watch the prices during the warranty period and decide what
to do.
