Its nice to see that the LEOs are not going to destroy it.....I saw on the local news a couple of years ago Philadelphia did a gun buy back program......the newscaster was showing a table full of handguns....amongts which were a Luger and a Broom Handled Mauser......I about cried thinking these were going to the melting pot.
Curious question: Where do they get the ammo for these old guns?...Must cost a lot for just a clip.. 
You can get 7.92X33 Kurz ammo for about $15.00 for a box of 20 Case lots of 500 are roughly $375.00 (124gr FMJ)

After World War II, the Soviet Union and other Eastern Bloc states supplied client regimes and guerrilla movements with captured German arms such as the StG 44 along with newly manufactured or repackaged 7.92x33mm ammunition. French forces discovered many in Algeria and determined the origin to be from Czechoslovakia. Examples also found their way into the hands of the Vietcong during the Vietnam War, and the PLO. It is still used in very limited numbers by militia forces in the Middle East as well as some countries in the Horn of Africa. StG 44s have been confiscated from militia groups by U.S. forces in Iraq.
It was used by Lithuanian partisans during the armed resistance against the Soviet presence, 1944–1953.
During the Syrian Civil War, a weapons cache of 5,000 StG 44s were captured by Syrian rebels in the city of Aleppo. Later, photos surfaced of the rebels using them in combat. <END>
Apparantly not that rare anymore....reported that the FSA captured appx 5000 STG44s in Aleppo. God only knows what will happen to them though.
