My apologies, this is just a matter of terminology. Let me clarify: while reliability testing, my friend ran into some issues with feeding ammo and with the ejector. Once he found the right ammo, and once Sig replaced the ejector, it successfully passed his reliability run. I'm calling the time he spent getting it to work properly his "break in period", separate from his reliability run.
On the other hand, my Walther P99 went for 2000 rounds without a failure out of the box - no "break in period" to get it working before it could pass a reliability test.
Hope that makes more sense
