Intermittent malfunctions mostly have no primer strike while a few had a light strike. I purchased this pistol recently which appeared to have very lightly fired. She ran flawlessly on the first two range visits. Same results with factory and my reloads. Is this possibly a known issue?

First I would check the hammerstrut. It might be bent or broken.
Yes it is a known problem.

Luc: I won’t be able to check for a few days. Haven’t been able to find a YT disassembly video or any online source for a hammer strut. I’m growing in my mechanical abilities. Do you know if the hammer can come out without any other parts being removed first? I did watch a disassembly of an auto mag II. Are you aware of any companies that still have hammer stretch for sale? Do you rather auto mag pistols in different calibers utilize the same hammer strength pen? Thanks and Vance for your help

You should first learn to take it apart, which I didn't think was a hard thing to do. If you want a step by step write up let me know and I can do it for you. Now that you have it apart, look at all the parts and compare it to the part diagram or take some pics of them and post here, maybe somebody will see an issue. Make sure you have a measurement item next to part to give reference to it, ie tape measure or mic.
The bent hammer strut was an issue caused by the owners by allowing the hammer to fall without the slide on the frame. The hammer didn't have a "stop" to hit since the slide was off and proceeded to move forward more than the strut was designed for thus causing it to "bend". Even when bent they would work but depends on how much bend was in it. I have an AutomagII with one and it shoots well, I was too afraid to try to straighten it as it might break with my luck so it still bent and I'm not messing with what works. Another issue might be your firing pin shorten/broken OR the firing pin shaft/hole is full of crud or gummed up. You can take your finger and push the firing pin forward (like the hammer striking it would) and see if you feel any dirty resistance or does it move smoothly? Let us know if any or this helps

Thanks XP. I’ve only removed the slide & barrel for cleaning. YouTube is my friend. I have not checked the firing pin. The guy I purchased it from never fired it. He purchased it many years ago for his dad. He never fired it. I’d bet it had maybe a couple mags thru it period. I never let the hammer fall with the slide off. I was wondering if the safety could be engaging. Hmmm now I’m wondering if one’s thumb could push the safety down during recoil. Sure would be nice to have a YT video. Do you know if the AMT II is the same dissassembly? That is on YT.

I removed the slide. The firing pin moves freely.

Ok, I’ll try to walk you through this w/o video. It really
isn’t hard at all to break this down to clean and check a few things. There are
2 ways that it can be done, not sure which is better for you or if there is any
reason not to do one over the other. Maybe others can chime in which is better
for what reasons.
Method #1 First, rack the slide with an EMPTY magazine in it, locking
it open, remove the magazine check the chamber to make sure it is empty/unloaded!
Now you can manually release the slide, I don’t let it slam shut on an empty
chamber, I just ride the slide shut slowly. Next you need to push in the recoil
rod plug to become flush with the front of the slide. You need to hold this in and
turn the barrel bushing clockwise (when looking at the barrel, good thing you
made sure it was unloaded, right!) almost 90 degrees, this allows the recoil rod
plug to now be released out of the front of the slide, going under that barrel
bushing edge. CAUTION: be careful
not to allow the plug shoot out and across the room or into your face! Slowly let
up on the plug until you feel no more spring pressure, now remove it from the
slide, then remove the spring from the slide through the front end. Next you
can slowly open/rack the slide (careful, there is no spring pressure on the
slide anymore so it will slide very easy, especially since the hammer is still
cocked) until the slide release lever pin/pivot lines up with the notch on the slide,
then pop the lever out going left of course. Now I hold the frame butt up allowing
you the see the bottom of the slide when removing it, this helps keep the
recoil rod and barrel together, carefully making sure not losing the pin/spring
inside the back of the recoil rod (if you have one). Then slowly move the slide
forward and off the frame. While removing the slide once you can see the recoil
rod I normally put my hand around the slide and rod holding it in place till it
is removed from frame. Once it’s off, you can slowly move the recoil rod
forward off the barrel block that it sits against and then you can remove the
pin/spring from the back of that rod. You must remember do NOT pull the trigger
letting the hammer slam forward! You grap the hammer with one hand, while
holding frame with the other, pull the trigger and then slowly lower the hammer!
Next you need to remove the barrel bushing from the slide, you now turn it
counter-clockwise back to the start position and then go 45 degrees more, if
you look inside the front of the slide you will see a nub on the bushing, it
must be exposed in the slide gap, now just pull the bushing forward and off the
slide. Now you can pull the recoil rod out from the bottom of the slide and
then you remove the barrel by pushing it forward through the slide and out the
front end. Method #2 First, rack
the slide with an EMPTY magazine in it, locking it open, remove the magazine
check the chamber to make sure it is empty/unloaded! Now you can manually
release the slide, I don’t let it slam shut on an empty chamber, I just ride
the slide shut slowly but STOP the slide when the slide notch lines up with the
slide release lever pin/pivot pin. While holding it there, pop the lever out
the left side. Once this is out, continue slowly moving the slide forward until
it has no more spring pressure. Now you can keep moving it forward until you
remove it from the frame, while doing this you need to wrap your hand around
the slide and recoil rod to keep them from shifting and maybe shooting that
pin/spring out from the back of the recoil rod. Once the slide and frame are separated,
you can carefully lay the slide assy. down and now focus on the frame, while
holding the frame in one hand, hold the hammer with the other hand, pull the
trigger and slowly lower the hammer down. Now back to the slide assy., you need
to push in the recoil rod plug to become flush with the front of the slide. You
need to hold this in and turn the barrel bushing clockwise (when looking at the
barrel, good thing you made sure it was unloaded, right!) almost 90 degrees,
this allows the recoil rod plug to now be released out of the front of the slide,
going under that barrel bushing edge. CAUTION:
be careful not to allow it shoot out and across the room or into your face! Slowly
let up on the plug until you feel no more spring pressure, now remove it from
the slide assy., then remove the spring from the slide through the front end. Now
you can slowly move the recoil rod forward off the barrel block that it sits
against and then you can remove the pin/spring from the back of that rod. Next
you need to remove the barrel bushing from the slide, you now turn it
counter-clockwise back to the start position and then go 45 degrees more, if
you look inside the front of the slide you will see a nub on the bushing, it
must be exposed in the slide gap, now just pull the bushing forward and off the
slide. Now you can pull the recoil rod out from the bottom of the slide and
then you remove the barrel by pushing it forward through the slide and out the
front end. Now I did
take mine apart and notice that while pushing the firing pin in (side that the
hammer hits) FLUSH with the slide the pin does not become exposed at the
breech, this is ok as the pin “pops” the primer by strike force. Next, using a punch
to check my pin on this next step, I pushed the pin into the slide and it goes
into the slide about 7/16 before it stops, the pin is not the same length out
as the punch is in but this give you a good look at the firing pin head, it should
by roundish. Also this allows you to get a good feel for firing pin spring
tension and if the firing pin is gummed up in its’ channel. It should move
freely and smoothly under spring pressure, no grit. Hope this
helped you. Maybe this would help others now that you already got yours apart. Maybe some can give feedback on which way is better and why it is. Both work ok for me. Hope I didn't miss anything, please advise if I did and I'll correct it, thanks guys (I know you guys will let me know too!) |

Thank you XP for taking the time to detail the takedown. That was as far as Ive gone in the past. I checked the firing pin, as you suggested, and it appears fine. How about removing the hammer strut? Anyone have details?

Did you get a manual with it? I'll see what's involved with the strut, really isn't that hard to work on these. The hardest part is dropping things and crawling around to find it. I learned to start with nice big clean area and work way over the table so when things fly/roll a little it still stays on table.
Still waiting to see pics of your work here, hint hint.

No manual but I printed one online. No instructions on removing the trigger, etc. All my family are in town so until I can remove the hammer strut pics are of little value. Slide is off with barrel on the bench for now.
