Here's to try and answer your questions.

Yes, the hammer struts may have a SLIGHT bend in it, but anymore and it starts to cause issues.

Yes, when reinstalling the slide, and the rod is bent like that, you can pinch it. Sometimes it works and falls right into place, other times it ends up poking out just a bit. I have found that even sticking out that tiny bit can cause it to not function properly. I always make sure its "perfect" or I catch myself chasing "issues" that may not really be issues.

As for the pins, now I don't know which ones I took them out of. Meaning, I didn't write down which firing pins went with which serial number. I assume what you mention about making the later versions with the stronger looking pin. These 3 pins are out of 6". I do have a 4.5" but have not taken it apart to see the pin. Now that I think of it, I will have to do that just to see and compare. Could they have gave them the hour-glass shape to take weight off the pin for operation? I am not a 'smith or engineer, I just remember a subject on another gun that talked about the firing pin weight. Maybe it was the Auto Mag firing pin? I don't remember. But I wonder if it has anything to do with it. Then they realized that making it beefier, and just notching it a tad, doesn't make that much of a difference? Maybe someone with a lot more experience and knowledge than me will know and help shed some light?

The 2 barrels on the right are actually barrels I bought around 2012-2014. One was from Numrich. I went to order another one and they didn't have any so I contacted High Standard and they sold one to me. The HS barrel and Numrich barrel look the exact same. I assume that they were from the same source. We all know that an original AMT barrel has the blow-back holes and the barrel is welded to the lug. The HS barrels look like they are pressed in (I know that would be stupid of them to do), but I can tell you that they do NOT appear to be welded to the lug. Maybe they are threaded? There are NO blow-back holes in either of them. I did a picture comparison in another thread on here a long time ago. I cannot find it to reference, but I attached some pictures below to show the different barrels and extractor cuts in the lugs.

I hear you about the ammo. 22WMR and 17HMR is just crazy. Mostly Hornady and CCI. I'll have to find a place and order some of the Aquilla.


These were taken at a time that I had my 4.5" AMT-II taken apart and I was comparing them.






This one shows the extractor notches in the lugs. The 2 on the left are the HS/Numrich barrels. Note how the notch is no where close to where it should be for proper function of the extractor. These prompted me to get out the Dremel and try to fix it myself.

If you were happy and you knew it, would you clap your hands?

This is the only ammo that would run in my guns.

Thanks Luv
Now I can tell the difference of them barrels, the HS/other barrels do not have the gas assist system in them so they didn't drill gas holes and weld the sleeve in place. Funny thing is they chamber opening still shows that they still cut down the barrel dia and sleeved it with the rear section/block. Wonder if they pressed it to keep it on or like you said maybe they threaded it on? That saved some work BUT what system did they do? How do the chambers look like? I once cut apart a barrel that was very abused and found a few things out about the thing. The sleeve is pressed on and even with the weld cut off I had to press that section off, was not a slop fit. Maybe your guys just figure it was enough with the 22mag pressure, not sure. Also explains why the extractor slots are different style then too.

Tony, I wouldn't be thinking of doing these for profit but just for the fun and learning of it. No guarantee of anything with it IF I get to doing them. I have a few ideas about making a few different parts my way to see if I can because I can. Never a business, way too much overhead issues with paperwork and other junk, you know it.

Ammo I use is Super "X" stuff but mine is really old so I know it's the right powder type as I heard they now changed it (maybe). My stuff was stored properly and has no issue firing.
Thanks guys for the info
