A friend with a major pistol manufacturer tells me that they use 155gr 40S&W ammunition for testing durability in their line of 40S&W pistols. Design engineers have nicknamed the 155gr round, the "Gun-breaker," identifying it as the one round that produces most wear and tear on pistols chambered for that caliber.
Of course, I personally carry Cor-Bon 155gr DPX in my SA/XD. It is my preferred, carry load, and I just ran several hundred rounds of it through my XD during the recently-completed NTI.
My XD had no issue with it. Neither has my Beretta PX4 Storm, S&W M&P, SIG229, nor my G23. It may well shorten the lives of all of theses pistols, as my friend indicated, but I am determined to carry the most effective ammunition I can, and, when my pistol eventually breaks, I'll get it fixed or replace it.
This is America. They'll make more!
