(from Dec 2013)
Fourth in a series of a quest to find the overall best ammunition for modern 9mm pocket pistols (such as the Sig Saur P938, Taurus PT709, the Ruger LC9, Kahr CM9, Beretta Nano, Kel-Tec PF9 or S&W Shield or any other popular 9mm micro-pistol using a barrel length of approximately 3").
In this installment, I am testing the Hornady Custom standard-pressure 124-grain XTP jacketed hollow point, part #90242. In this test, the ammo performed fairly poorly, delivering minimal expansion and three of the five rounds exceeding the maximum 18" requirement. Because it exceeded the maximum, I'm ruling it out of contention, but I will acknowledge that overpenetration is better than underpenetration, so it's not that this is a terrible round... I just have found other rounds that perform better, so there's no need to continue testing the Custom 124-grain round. Also, annoyingly, the chronograph failed to register speeds for three of the five rounds, so we only have chrono readings for two of them.
Note: I'm not making any claims for these videos other than that these are the results I achieved, in my own testing, from the stated pistol. I have no intention to make a blanket endorsement or indictment of any product, only to review and report what I found in a given instance. Obviously it is incumbent upon each individual to conduct their own research and make up their own mind about which defensive ammunition is best for their own purposes, in their own firearms.
The purpose of this testing is to find which rounds of ammo perform well enough from a short 3" barrel that they can reliably deliver the penetration (with expansion) that has been documented and proven necessary in order for the bullet to be able to reach the vital organs of an attacker and deliver an incapacitating hit.
