From the 1911forum:
"FN HP-DA Compact
There is a new and very limited model available through FN Law Enforcement channels. I know this because I just got one directly from FN through my business relationship with them.
It is the new FN HP-DA that was reviewed in American Handgunner a couple of issues back, except it has a 4" barrel and a shorter grip frame to accomodate a 10 round magazine with no extra. They only imported 80 into the US so far, and I understand the production run is only 800 total.
It's distribution through LEO channels is a bit strange because there is nothing legally limiting, it's just a very limited production and they thought that would be the primary interest area and they have distribution control there.
You know, I actually no use whatsoever for it, I bought it just because it is unique and offered to me. It is neat, a double action, commander sized, made in Belgium FN HP."
