Mine fed two boxes without a hitch, however, I found the round to feel weak (no actual evidence) when compared to Corbon PP, Rem GS, and just about any other ammo. However, only Santa Barbara actually caused enough of a trigger slap to be painfull.
Some swear by DPX, while some tests have shown DPX to be underperforming (in 380) also given the cost of the ammo, I am just not sure I would go with it.
