So here's my big post of the year.
I've been working on this for the past 4 months. Pump once, fire 3 times semi-automatically. Gets 50 feet of range. The gun weighs about 9 pounds. I still have some work I'd like to do on it before I post instructions. One of the things I'd like to do to it is double the capacity by adding another revolver wheel and draping a longer ammo chain (about 36 rounds) over the two wheels. The second wheel would go directly under the current one.
The section that sticks out in front of the pump is to rest it on things. The white connectors on the butt prevent it from sliding up when cocking and down from the weight. It uses an alternating trigger system and three barrels. It also uses a new system for spinning a TR-18 turret.
Hope you like it. It takes a butt load of parts though.
Check out a video of it here.

Oh and by the way; AWESOME PIECE OF EPICNESS
Sorry, I had to.
mech allow the three pins to fire in succesion, allowing for three shots of semi auto?
It's a shame I don't have enough parts though, I'd love to build this!
and once again, great job. i especially want to see the trigger system, and the way the pump is held in place (i just want to compare it to my system of holding the pump in place). i hope you can get the 'ible out as soon as possible. even if you could just take out the outter layer of the pump area to take a few pics and post them in our SA v9 working area, i'd be happy.
Therefore, you can cock one or two barrels and continue firing as normal without the gun malfunctioning. This would allow you to go from having 1 or 2 shots ready after firing to having 3 shots ready at all times.
Or in short, the answer to your question is yes.
Yeah, I can do that , when I start the mlcad model I can get you some images of the pump at the least. The trigger system will take some time to accurately show however. You might have to wait for the instructable for that part.
In the meantime, can you maybe make a sketch of the trigger mech so I will be able to understand how it works and perhaps try to utilize it on the SA 3252?
By the way, remember I promised you I'd have a lot of time in mid December because of a holiday? Well it's here ! I have a ton of free time this week. I think we should try to use as much time as we can this week to take a step forward with the project. My holiday will be over by next Thursday.
Yes, I'll do a sketch of the Z3 mech for you. It's basically a stronger version of the alternating mech.
Now here's a challenge and a request, think you could figure out how to make an RBG pump system? That is, take the average RBG mechanism with a cog or gear, and then add a pump that would load a band (maybe more than one?) per pump. Obviously, this would make semi auto slings much more popular if it was much easier to load them. I don't actually think it would be hard making a pump system to drive a band into a cog and setting it, but the trick would be somehow separating the bands at the front of the gun without them getting in the way of the bullets.
There's an idea! I'll do some thinking on that.
