AMT produced all stainless guns back in the day and was founded 1977. They created a very small semi-auto pocket pistol the "Back-Up" intended for law enforcement use but popular for civilians as well.
This tiny semi-auto was designed to slip in a pocket and used for close work. The all stainless design makes it rust resistant. The sights are fixed rudimentary channel type. It has a single action trigger with a depressible grip safety (1911 style) and a manual safety on the left side of the frame. The frame grip is rather small and the magazine has a hook/pinky extension.
AMT had issues with working on stainless steel and some frames and slides were of the same stainless steel and would gall the metal and lead to malfunctions. I use RIG stainless lube/grease to avoid galling and insure the frictional areas are well polished.
Pros:
It was a reasonably priced gun back in the day.
Easy to conceal very small all steel pistol.
Rust resistant.
Neat looking and attractive pistol.
Cons.
This example was a jam-o-matic. It was unable to fire semi-auto with any ammo. But it's fixable, see details.
Grip is tiny.
AMT went bankrupt. This particular model is no longer made.
.22 LR is not a great caliber choice but better than harsh words.
Without further ado here are the pictures and an explanation of how I got this gun to run for the first full magazine ever. More testing later.
So the issue was failure to go into full battery/lockup-fail to feed issue.
So the areas that can use a bit of help;
The feed ramp can be polished.
The extractor can be polished and a radius can be applied to sharp edges. I angled the extractor a tad sharper to allow less lifting on the extractor to enhance lockup.
The extractor channel on the bolt can be polished and smoothed out. I used a small rod wrapped with sand paper to accomplish this.
The extractor channel on the barrel hood can be smoothed out a bit. I used a tiny file wrapped in 400 grit paper to smooth the extractor channel.
So to break this pistol down, use a non-marring punch (plastic, brass, aluminum etc.) to punch the take down pin out.
Once the pin is out retract the slide a bit and the bolt with either come out on it's own or a non marring rod inserted through the mag well can tapped on to loosen it up and out.
Take down continued. The hammer will need to be depressed to release the slide forward.
