I Have An AMT .380 S/A
Bought it used, and after about 500 rounds of various manufacturer's ammo, this one had about a 1% misfeed rate, and they were almost all when dirty. Yesterday I broke it down and polished the feed ramp to remove any hint of milling marks, and went 50 for 50 this afternoon. You need about 500 rounds to readily and repeatably get your sight picture, as the sights are effectively non-existent. I find it easiest to make like I'm sighting down a piece of celery, and when all I can see if the U-shaped curve at the rear of the slide, it's as close as it's going to get. There just isn't enough material in the front tit to work with.
The safety sucks. If the lever is just bumped out of the "safe" detent, you can fire it. For that reason it's best not to carry it with a round chambered, which pretty much defeats the concealability benefits. Haven't had a problem with the magazine latch, but it is exposed and could conceivably leave you holding an empty weapon when you need it most.
It is surprisingly accurate for a short-barreled weapon, it's built to last (All stainless) and it will fit under the average wallet. The issues I have with mine are all design-related, and not workmanship problems. Mine was built at the Covina factory, so that may have something to do with it not being a POS. They're a PITA to tear down compared to other weapons, but it's well worth doing.
