Recently I bought two Super Soaker Triple Shot Waterguns, and I was very impressed and astonished. The nozzle setting is great and the stream is very laminar, best of all is its biggest stream( 5 X:: ? ) which is very powerful and strong with great range!
Well, then I was very depressed by the gun's main problem: THe reservoir is emptied in seconds, using the big stream you get 1 second of shot. In this one second the stream archieves full range and drops off within the second. Leaving someone with two big shots and much pumps. Well, this is a great sidearm or for a fast and heavy attack. But that is it and then you have to refill and pressurize again... -.-
But the nozzle selector and the big nozzle were so interesting to me, so I planed a modification on it. After a little work, I finished:
In Short I was doing a big PR-Expansion, the simple solution to the whole problem!

NOTE: Gun is not empty but at this point pressurize is starting to drop off. Time to pump in air^^
May get better shots with 3/4 filled gun as you can pump in more air --> leading to a even better CPS character; The gun does even have a recoil now

datas: Reservoir was expanded to over 1500 ml
Firing time on big nozzle: Over 8 seconds( over 5 seconds of steady stream at a range of more than 10 metres)
It is very impressiv, what you can get out of this small gun! Haha, while being very kompact and small, you can run and evade very quickly and then give your aim the full power of water! Pressure is great, power is exciting!
Get a triple shoot, do a small modification and beat up even big CPS users! Doing a fast attack may leave someone drained a little bit but then you can soak with full power and waterstream size! Nobody will think this of this "stupid and weak" Triple shot!
Great thing in less than one hour

Besides, easy to reconstruct the original gun if wished. No reason for this though as the performance is more than 3 times better ;D
