This is a very easy pistol to modify. First, take it apart. It's very simple on the inside, huh? You can start by stretching the main spring in the plunger. It is hard to get back together afterwards, though. Now, inspect your weaker barrel. It should have a hole in it. Those fools. Put some duct tape or hot glue on that pesky hole. See the green thing that diverts the air between the barrels? You can take it out and seal the barrels to the pump so they fire at once, but it will fire shorter and not give you an extra shot. I recomend leaving the barrel selector alone. You can hot glue all the connections, so there are NO leaks. Don't use too much hot glue or you'll clog the holes all together. Now put the gun back together. You can leave out the ammo holder/fin if you want to because it looks dumb. It is hard to get back together because it keeps trying to pop back out. Now load the gun with a magnum and shoot you brother. If he gets knocked through the wall, you did it right. If it goes through him, you made the gun too powerful, and should compress the spring again.
Feel the power!
