I have a ported 40 and a match 38 super. My shooting buddy has 2 match 9's, a match 10, a 40 , a 45, a 10mm and I believe a 9mm.
Of all of those guns, the only problems we have had is sights falling out of the dovetails, lost grip screws and a few bum wire-cut 10 rnd 10mm mags from the clinton mag ban days.
EAA has some issues with some folks. I used their customer services for springs and spare parts with no issues. All of the broken mags and lost sights were replaced free of charge.
