Can't find it around here & the one on-line source I buy ammo from doesn't alway have it, so I've settled on the Winchester PDX1 in my .380. Both it & the Corbon DPX did well on expansion & penetration in the tests I've seen. On other calibers, I prefer the Federal HST as it comes 50 in a box for just a little more than the 20/box DPX. They also got good reports on the tests I've seen.
I will say that the Corbon DPX has proven good in all calibers & regardless of pistol size, etc. so if I wanted to have just one brand for all calibers, the Corbon would be it.
