My wife's 9s was not fired before the recall, so I can't do a before and after.
It had a real serious problem with dbl feed. Didn't matter who shot it, and it would jam up real good, requiring two people to unjam it.
I was using commercial reload HP ammo. It runs through the XDM all day long without breaking a sweat.
I took the magazine apart, and discovered the follower had a burr that dragging on the inside of the magazine. Smoothed that off and added a touch of grease, mucho better. Also ran some commercial SD rounds through, no problem. Then I fired my own reloads through, no problem. My reloads are right in the middle of the recipe, and are significantly snappier then the commercial reload. Me wonders with supporting data if they were loading the rounds too light, and the 9s doesn't like wussy loads?
I found it to be surprisingly accurate for a small firearm.
