There is a technical aspect to this I don't claim to fully understand. The tolerances, protrusions, lug engagement, bolt rotation, BCG travel, battery station, spring rates, cycle speeds, etc are variables that play nicely with each other until they don't.
If I had to guess, I'd wager that you're seeing the result of a new bolt and BCG. There was likely a burr or other production issue that has since either worked/worn itself out/in, or something wound up magically between the pin and primer on the initial bolt closure.
Can you reproduce the conditions and effect? I'd spend some time trying to re-induce the slam fire before I fully trusted the setup, there are as mentioned lots of potential causes of the malf.
