Stock P320, about 800ish rds, factory mags it came with.
If I fill the mags with 17 AND the gun has been sitting unused for weeks, I will get light primer strikes (fail to fire) on first 2 rounds of magazine. However, after firing a few mags, I can load both mags to 17 and it will run all day long.
But this has happened on 3 separate range trips & took me until yesterday to catch on.
No grease or anything out of the ordinary - just RemOil I think. Possibly CLP, but I don't have the striker assembly or channel all gummed up with grease/crud/funk. Reasonably clean overall.
Looking at the underside of slide, it doesn't look like a full mag should be able to put pressure anywhere to cause excessive striker drag & give light strikes, but it seems like that is exactly what happens. A factory 17 rd mag only loaded to 15 will fire perfectly "cold".
When it does this, the 2 rounds it fails to fire have very light indentations on the primer - looks about like when you chamber then extract without firing a round from an AR - that little firing pin dimple on the primer from an AR going into battery - that's about what these light strikes look like. And very obviously lighter than a piece of fired brass and the indentation on that primer.
