It's not fun but it's not too difficult. I just took apart Kamicosmos' the other night. To get the slide stop out you have to pull the slide full back and lift the slide stop up before it will come out. Slide comes off foreward.

Be careful because the ejector will just fall out at this point.

Slide bushing comes apart like a 1911 but the barrel comes out the back.

Everything else is retained by pins and springs. Just be careful and they should be fairly self explanitory.

As always DON'T FORCE ANYTHING. If it's not coming out there's a reason. You'll need a punch to get out some of the pins but they shouldn't take more than hand pressure to remove.

Don't have his gun here or I'd get some pictures for you.

Thanks.......wasn't sure what position the slide should've been in to remove the stop.....that got it! This one has had trouble with extraction - the inside of the chamber looks like it has raised spots in it for lack of better you remember anything like that? I can't tell if it's bad manufacturing or if they intended to put'em in there.....they are evenly they left part of the rifling in spots but spaced evenly around the chamber area ???? I've never seen a chamber anything other than smooth and can't imagine why this one is like it is other than a manufacturing defect.

Thanks again,

Those are supposed to be there. Some barrels have holes drilled full through the chamber. Somehow they're supposed to keep the brass from sticking in the chamber.

Thanks again........I don't understand it though, seems like they would cause the brass to stick instead of not ????

Here's a site for a manual.
Or this one of a Microsoft Word document.

I know this thread is very old but I recently got an AMT Automag II, one of the earlier ones from the original company. I read this post and the instructions for getting the slide off but I could not do it. The tension on the spring when pulling the slide back is very stiff and hard to keep back while trying to pull the slide stop out. I tried several times but even when I was able to keep the slide back I could not get the slide stop out. I do not know if anyone has ever taken it apart. Could it just be stuck from poor, prior gun cleaning?

Any help would be appreciated

The chamber flutes are supposed to allow powder gas to get between the expanded case and the chamber to allow easier extraction.

HK used the same principal in the CETME based HK91 rifle and P7 pistol.

I have never heard of any with holes drilled clear through the chamber.
That would not work, as the fired case would, if not blow out, expand into the holes and be firmly locked in place.

BTW: The Automag II was designed to work with Winchester Super-X .22 Mag 40 grain ammo.
It is doubtful you will get them to work well, or at all, with anything else.

Here's a link to the manual for your pistol:
Try the procedure as described in the manual.

thanks to several people for their replies - It was helpful and I was able to finally get it apart. The trick was to truely lock the action open with the slide stop up then push the slide stop out by pressing on the pin from the opposite side. It just slid out easily once it was in the right position. I don't think it had ever been cleaned in the broken down position as there was dirt and debis in all the crevices. The gun was very thankful for a good cleaning.

Have a great day.

I am wondering how you remove the firing pin. I need to remove and clean the carbon build up out so the pin will move freely again. if anyone know how please let me know thanks.

I think the sight has to be removed
