Hi yall
I burnt out my microswitch on my UDL P320, so I ordered a new wiring set from M416gelblaster. (Its the exact same as the stock wiring). I put it into my pistol but now each time I shoot it it the gears overturn, pulling the slide back a little (about 2-5mm). I’m not 100% sure if that is the problem, but it seems like the most likely option. Because the slide gets pulled back a little after each shot, the nozzle pulls away from the barrel, making there be almost no air seal. Now, it barely shoots 5 feet. I was thinking it could have been an error with how the circuit board was programmed, but if any of yall have a suggestion, it would be greatly appreciated.
I thought P320 typical things were firing without pulling the trigger!

I would guess it is more likely that something is out of timing, as usually stock circuit boards rely on switch signals triggered through the cycle.
So once a switch is contacted, the board will cut the power until the trigger switch is released etc.
There might be different versions too? Not sure as haven’t had one apart here yet.
If you have any pictures of it’s insides may help us understand it?
Thanks Rok, I appreciate the advice. After playing around with it a bit more, I think the circuit board is on some sort of timer, so when the trigger is pressed it spins the motor for approximately 0.5-0.8 seconds. In the last two photos, if you look at the edge of the gun, there is a small triangular tab sticking out, right above the metal “button”. This is so that the trigger catch can still catch on the piston while the trigger is pressed. I thought at first it switched off the circuit, but I was wrong. In the 6th photo, under the trigger catch, you’ll see a white thin button. Instead of allowing the electricity flow to the motor, it indicates that the gun has been cocked and therefore allowing the trigger to respond when pressed. In the 7th photo, it shows the button compressed. Photos 10 and 11 show the trigger switch, which allows the electricity to flow to the motor, if the piston has slid over the catch, compressing it. In photos 12 and 13, I just show the circuit board and the full gearbox. Hope this helps!
Seems the Chinese are so good at cloning the real steel counterparts they even manage to clone the faults as well! 
It wouldn’t be a Sig P320 if it wasn’t problematic
