Default Help! Amt automag 3 .30 carbine

I have a quick question for you guys I want to pick your brains. I have a Automag 3 and its doing kind of a dangerous thing.

If you have the slide locked back, insert a loaded mag. Then you drop the slide it fires.
But if you pull the trigger then drop the slide the hammer stays back and dose not fire. If you insert a mag then manually chamber it. It dose not fire. Only when you drop the slide using the slide lock/release tab
I took it completely apart 100 times can not figure out. Would it be the shear spring? Or the thing the actuated the hammer? The shear hammer? Let me know what you guys think.

You are getting slam fires. Anyone who uses 1911 pistols should know to never let the slide slam a loaded round. The hand is used to slow the travel of the slide when you push the release. You may have high primers a fowled chamber a bad disconnector a swelled or carboned firing pin. But start by proper slide release.

I agree with Durangokid.

BTW, I want that gun. If you ever decide to get rid of it let me know.

That dose make since but I always used to drop the slide with a loaded mag. It just started doing this....
But I totaly agree I will soak and really clean the chamber and firing pin. Those are some great tips

Almost sound like a broke firing pin.
Letting the slide slam forward allows the pin to move.
Trying to hit the pin with the hammer, and no bang, mayby that pin is sheared.

Suggest a new firing pin, spring, and change of habit.

When the slide is locked back, can you see the firing pin sticking out at all? I mean out into where it would hit the primer when it goes forward. Don't be insulted by the question. I have no idea of your gun smith skill level.

To add to Rick's suggestion, you may want to try and activate the pin movement while you have the slide to the rear and see if the pin sticks out at all.

(A dull pencil end will move the normal working pin enough to see if it moves and retracts correctly.)

Normally, there is enough of the firing pin spring to keep the firing pin off of the primer. If the pin is broke, the broken tip may have enough inertia to activate a primer when allowing the slide to slam forward. And the spring is keeping the broken rear half enough off of the tip during normal firing to work properly.

Durango and whoever agree with him...WTF? YOU NEVER RIDE THE SLIDE CLOSED ON A SEMI-AUTO PISTOL. Recommending the practice is very foolish.

I agree the broken/frozen firing pin posibility.

I would assume firing pin issue also.

Agreed on possibly pin. It dose have play. Maybe spring. I want to remove the whole assembly and inspect the spring and do a deep clean on it. It dose not seem seized.
I agree and will not slam load it anymore. It's just doing slam firing.
