It's not that hard. I've done it to mine and it's really short (got a lazy trigger finger) but still safe (no bouncing shots).
Go over your Angel's manual or
http://angel-owners.com/index2.htm[/URL] , it pretty much guides you over the disassembly/assembly procedure.
Just take extra care when re-attaching the grip to the main body, as you could damage the connecting wires.
The ****ty part is that you have to put the grip against the main body every time you have to check if the trigger operates the micro-switch (that activates the electronics)correctly (it's try-and-error method).
The adjustment is really just setting two Allen screws that limit the travel distances of the trigger:
- Over travel, top screw: How much the trigger presses into the micro-switch. Turn counterclockwise to shorten this travel distance, but not to much or the micro-switch won't click-on (gun won't fire).
- Return stroke, bottom screw with a spring on top: How much the trigger goes back after clicking the switch. For lazy guys like me, keep this short. Too short and the switch will not click-off (reset) meanning the gun would only fire once.
Hell... sorry for this long description. Hope it helps.
