M9, relieved
The Beretta M9 Tomb of the Unknown Soldier variant has been used to conduct over 100,000 wreath-laying ceremonies and has been carried by NCO Sentinels on 279,850 Guard changes. It has been replaced by the new Sig Sauer M17 Tomb variant.
In this video, Soldiers from the 3d U.S. Infantry Regiment (The Old Guard) received brand new ceremonial M17 Pistols replacing the M9. The pistols were specially made to uphold standards of the Sentinels of the Tomb of the Unknown Soldier.
