So, easy hack-job for making a Masterkey that's a couple inches shorter, is you can go ahead and eliminate the trigger and trigger guard. To fire it, you just poke a finger into the sawed-open backend and pull downward on the convenient lower deck of the plunger catch fork.

Not very elegant OR convenient, though.

So to make the slam-fire automatic, there are two options I came up with, but both require some fabrication (cutting, gluing, adding angled pieces, etc)

1. Extend the "done priming detector" piece with more junk hanging out the back at an angle, such that it forces the plunger catch fork downward when it gets pulled forward, OR

2. Re-spring the plunger catch fork the opposite direction, and repurpose the "done priming detector" to force it upward to catch the plungers with an additional angled piece of plastic. The more I think about this, the less I like it, because the plunger catch fork has to "give" when the plungers move back to latch in primed position, so the original spring direction makes more sense.
