mes, I'm a little late on this, but will share what I know. I used a few thousand rounds of the 9MM +P version, packaged loose in 250 round boxes. I never experienced an issue or failure of any kind while using this in different pistols, revolvers and cabines. Wish I'd bought a ton more of the stuff. I chronographed it, and found it displayed the same ballistics as any of the regular production Speer 124 Gold dot +P ammo. I researched it at the the time and, IIRC, during manufacture, a slightly different primer was integrated into production. While there were no known failures, when discovered, Speer realized they could not warrant the ammo to LE as performing as with the previous primers. They then packaged it in bulk, with the not for LE use disclaimer, and sold it as practice ammo. It was not scavenged duty rounds, etc. All I bought was was as clean, bright, factory fresh as any purchased in the regular 20 or 50 round boxes would be. While all of mine was the 9MM +P version, I remember seeing the .40 S&W and Non+P 9MM versions being available at the same time...
