I will try to talk you through a disassembly, to begin remove screw holding trigger guard, front of guard is around a pin in the front, tip forward and lift, it will come out. Remove the four screws on the sides of the grip, remove screw in bottom of the grip, lift action out. Remove little screw then big barrel pivot screw . Slide cocking arm to the front of the slot and tap out pin, it is bigger in the middle so center it in the cut out. Remove screws holding rear sight, put in spring compresser and look at the pin, it's at an angle and one end is bigger, tap out from small end, release pressure and remove rear cap and spring, slide piston to the rear until it hits the release for the trigger, push release out of the way and pull out the piston. That should have it apart.....to increase velocity reduce transfer port to 3mm, I have some tubing that works perfectly for this if you want some, I tried a cut down spring for a B-26 in the pistol, all it did was make it really hard to cock and only gave about 50 fps increase so it's easier to do the insert for the port, get about the same increase...notice how to adjust the rear sight, it just tips depending on how the screws are tightened...
