So I recently traded for a brand new Metro Arms Amigo (compact). Took it to the range and fired ~88 rounds. First two mags were pretty good, but from there on out is snowballed. Failed to return to battery multiple times, but a little tap on the rear of the slide usually took care of it. Then it hung up out of battery once but wouldn't return to battery manually. Hadn't stripped a round out of the mag, either. I removed the mag and tried to put it back and lock the slide, but it wouldn't go back far enough to enable the slide lock. I had to disassemble it and it actually hung up and didn't appear to want to come off the frame. I completely disassembled it finally and found that the reverse plug was deformed due to some sort of contact (not hardened?) and the spring was kind of boogered up. I got it all back together and it appeared to work fine, but the failures to return to battery continued at least 3 times every magazine. I noticed it didn't lock back after the last round and my aim was getting worse and worse. Turned out it would no longer come all the way back to lock the slide open and the front sight had come loose. Jeeze. I have returned it and I'm waiting on another one to come in to see if that one will work better.
