The Angstadt UDP-9 is a sweet little gat. When you add a Law Tactical Folding Stock adapter, this thing can disappear into almost any bag, and be ready to deploy at the flick of a wrist. I've really been enjoying these little Pistol Caliber Carbines (PCCs) lately. I've been a huge fan of the AR platform, I think the controls / ergonomics are second to none - so the desire to own an AR that shot 9mm from my abundance of Glock mags has been appealing for quite awhile. The Kriss Vector kind of brought me into the PCC fold, but the Angstadt UDP-9 made me stay.

While there are some obvious cons to shooting 9mm from a carbine (it's weaker than any other rifle round that ARs typically shoot), there are some definite pros as well. It shoots the exact same ammo, and mags, that my carry gun (a Glock 19) uses. I can shrink the barrel length well below anything that I'd want to shoot a 5.56 out of, and still maintain the bullet characteristics and ballistic performance that the round (any 9mm) was intended for. Overalll I think AR9s are pretty sweet, and the Angstadt UDP-9 is one of the best out there.
