Maybe I'm not being entirely fair, but I've had poor results with CorBon in previous limited tests with the P32. Also, their ammo is usually a lot more expensive than Speer or Winchester JHP. So for the price it ought to perform better but it didn't for me. CorBon failed to expand 3 times out of 4 in my last .32cal test while Win Silvertip expanded 4 out of 4, Speer 2 or 3 out of 4. On the Marshall site it was reported that the CorBon .380 failed to stop and was not recovered (meaning it probably didn't expand at all). I'm not sure but I think CorBon only makes .380 in a +p 90gr JHP. And if this is the case, I will not even include it in my future tests. I just don't think the KT P3.. pistols are intended for +p although many have tried it, the bang and recoil is enough with std. ammo. The FirearmsTactical site did not test it and neither did AmmoLab.
And I know Goldenloki shows good results for .32cal CorBon, but he tested a new, longer OAL round than I did. I have not been able to find any CorBon .32 with a long OAL like he did.
Wish Goldenloki would do the .380 tests with the P3AT. His data is the only info I trust.
If there is enough interest I will repost my non-ballistic, unofficial, hollowpoint expansion test data here on KTR.
