I've got the EAA Stock 10mm, and it ran perfect straight out of the box. My original EAA was a Witness 10mm, and it required some work on the feed ramp, stronger recoil and hammer springs, and polishing the inside of the mag body and Wolff +10% mag springs. Still, for $349 NIB, it was a hell of a deal.
Oh, and I have a 45 EAA Witness that I worked all the way up to 45 Super, and out of a 4.4" barrel it will throw a 185 grain Hornady XTP at 1260 FPS.

Same mods as above in addition to Magnaporting and a Sprinco 10mm recoil buffer...
