I have a base model in Wonder Finish in 10mm. I love the cartridge, personally it is my favorite. It is my woods gun with Double Tap 230 grain WFNGC filling the tank.
I've had a few issues with mine.
1. A bad mag release, easy fix, but still
2. Had to goto +10% mag springs before it fed reliably.
3. I put in a stiffer recoil spring. Need this for anything beyond the long 40S&W cartridges. Which, unfortunately, is most of them off the shelf until you get into the boutique manufacturers like Double Tap, Buffalo Bore or Reeds.
I did a fluff and buff on it and shortened the ejector some. Still, the thing hurls brass about 20 feet. But it used to be 30 feet.
I did all of the work myself and am now happy with the gun. Hearing of EAA's customer service, I took my own chances. I'm a gearhead, so this was basic stuff. There is a lot of good info about them on
http://10mmtalk.com and I have posted a lot of info on my fixes. I have the same nickname there, peruse the site for some more background on these guns and a lot of specific issues and how they are handled. The mags dropping seems to be a common issue, and the fix is really easy. Everything is easy work and worth doing if you have a file and a dremel with a buffing felt and a bottle of metal polish.
This is usually a gun for the reloader types because the cartridges are hard to find in retail locations. Sure, you can get all you want online via the boutique providers. But if your out in rural America and run out of plinking fodder, you won't find it at your average gunstore or sporting goods shops. Trust me on this, a 1400 mile round trip from Oregon to Colorado and I hit at least 10 or more stores, most did not even know whether it was an auto or revolver cartridge.
