Mark IV extra parts

So I bought a new Mark IV Target and I'm cleaning it, getting it ready for Froglube. I did a service tear down, upper, lower, bolt, grip panels, nothing too intense. I'm getting ready to put it back together and I notice I have extra parts. I figured that's probably not a feature.



Here's the extra parts. A spring, a plunger and a thing-a-ma-jig (the dime's mine).

The TAMJ I think I found a home for at the bottom right of the frame.



But as for the spring and the plunger, I have no clue (about where they go, I have lots of other clues). I've almost memorized the exploded view in the owners manual and the nearest I can come up with looks like are from the upper diagram, numbers 8 and 9, rebound spring and rebound spring and guide rod.

Whatever they are, I did not knowling remove these parts (actually had to search for them as one of them hit me on the foot). I'm pretty sure I've found all the "extra parts". And I'm guessing the spring and plunger have nothing to do with the TAMJ.

HELP!

That is the mag ejector. It is designed to help eject the mag when you press the mag release. Put the spring in the end of the flat black piece and put the plunger in the end of the spring. Depress the spring and plunger into the flat black piece and put the entire assemble into the space at the bottom of the frame. The spring and plunger gives the mag ejector the force it needs to eject the mag.

You can see these parts in this video.

Thanks so much! You're a lifesaver!

one of my favorite things to say while working... (electro-mechanical field service) is...

"10% of those parts, we don't even need"

but I did the same exact thing, while I had the grips off. luckily I found all three of the parts on me, and the carpet.

Thanks. I'm glad someone else admitted to the same thing!

I spent 10 years (ages ago) as a motorcycle mechanic and have built my own 1911 (it's posted here somewhere). I was determined this gun wasn't going to beat me, but I wound up having to ask for help. Happens to all of us.

I must have looked everywhere for the right sized hole for those to fit in, except the end of that mag ejector.

Oh well...

BTW - those parts are not shown in the owners manual.

you watch this video it shows those parts. They go under the rt. side grip panel and they kick out the magazine when you push the button. The video says if you install the VQ accurizing kit you don't need these parts. This is shown at 24:53 on the video.

Thanks. Actually I don't think they're needed at all. The mag spring is the primary ejector.

That is what was said in the video - not needed. But, a little more force to eject the mags. Try it both ways and see which you like.

Hate when that kind of thing happens!

I know my limitations. Maybe that's why I favor revolvers over semi autos.
