Or use a revolver.

Oh, the horror!!

Last year I encountered an out of spec oversized case in top quality defensive ammo. It was so far out the slide wouldn't go into battery even with considerable force behind it.

The best policy is to drop each cartridge you plan to carry for defensive use into a cartridge gauge block like the ones Lyman makes to make sure they'll feed when you need them.

I bought about 10 boxes of ARX Inceptor 9mm ammo from Ammo Shop Online and took it to the range along with my S&W M&P 9MM EZ pistol.

I discovered that the case diameters of this ammo are inconsistent and caused failures to go into battery. Some would feed into the chamber, some would stick going in, and some wouldn’t go all the way into the chamber at all, even with strong pressure. After 4 failures in the first 15 rounds, I stopped using the ammo.

I confirmed that the issue was with the ammo rather than a tight chamber in the pistol by checking the rounds with a Lyman cartridge inspection block which showed the same issue when some rounds would not drop all the way into the 9mm hole. Micrometer checks showed a variation of several thousandths in case diameter among rounds.

I sent a message to ARX through their website and an email to the vendor and asked for a response on how this should be managed. Both failed to respond at all which led me to believe they were aware of the issue and didn't want to acknowledge it.

Needless to say I won't be using either that ammo or that vendor in the future.
