I've got a little less than a thousand rounds through my EMP-9, but I had to send it back to Springfield for a few issues.
The pistol came from the factory with an extractor that put absolutely no tension on the casing. I fixed this one myself by tensioning the extractor. I don't believe Springfield test fires these pistols before they leave the factory. After I fixed this issue, I haven't had a single malfunction with it.
The hammer was impacting the sear while passing by the intercept notch. This one didn't cause any issues while firing the pistol, but I didn't like it being there. Springfield fixed this one.
There is also the issue of the top round in the mag impacting the ejector when inserting a loaded mag with the slide locked back. I say "is" because Springfield didn't resolve this issue when I sent it back to them. I sent a note along with the pistol that stated the issues, but I guess they forgot to take care of this one. Now when a mag is inserted, the brass on the rear of the casing on the top of the mag has an indentation that matches the edge of the ejector. I think I may take a file to it and shave a little metal off myself.
On the note I sent with the pistol, I asked that they pin the ejector in place (I don't like the idea of a glued ejector, especially when the top round in the mag impacts it every insertion), and they did this for me, for free.
So, I don't know that I would recommend this pistol to someone who wasn't a gun guy, or wasn't willing to go through some hassle to get it working right, but it is easy to shoot accurately, and it shoots surprisingly soft for a pistol this size. After I put about a thousand rounds through it (after I fix the ejector issue), I'll consider carrying it on occasion if it functions right from now on.
