I have an early .380 AMT single action backup. The positives are the gun is still one of the smallest .380's you can buy, VERY concealable. Mine also has no problems feeding and firing. Its a nice little carry gun, but it does have some drawbacks.
The negatives....even the gun's owners manual recommends NOT carrying the weapon with a round in the chamber. The firing pin is NOT blocked, and the hammer (concealed in the body of the weapon) will be cocked back, ready to fire. My safety lever broke at one point, but at the time AMT was still in business, so they sent me a new safety lever.
I once diassembled the firing "block", which required punching out a retaining pin. Never did that again...once the pin was out, I had to go to Ace Hardware to get a new pin. Just used spray cleaner from that point on.
Since the gun is not backed by its manufacturer anymore, I would not get it, even though mine has been "ok". There are superior products on the market now. Still...I must admit, when the weather is very hot, and you are just wearing shorts, it is great to have a .380 small enough to just slip into your pocket...
Mine may be great, but others may be bad...
There are superior choices, even if not in .380. The KelTec in .32 looks superior in design to the AMT.
(I also replaced the screws in the grip with regular sloted ones...they had some weird hex screws in mine. Another trip to Ace Hardware)
I take it this is NOT going to be your first gun, correct? If it is, there are MUCH better choices...
