I have a box of Hirtenberger 9MM amm, but its 100 grain not 124. Its marked 100 grs SOFT POINT FL-BULLET, Law Enforcement Grade. I've shot about 50 rounds of this stuff through various 9MM pistols, but a few years ago. I don't remember the recoil being bad, maybe due to the light bullet. Shot fine. I assume this is not the subgun ammo the BATF is warning us about. The case is stamped HP, +p+, 9MM Luger.
