hi guys, I am new here and i am hoping to get some guidance. I am trying to wire some guns for my arcade cabinet. inside the plastice housing there is a 12 volt soleniod that acts as the "recoil". I need a "one shot" circuit so when I pull the trigger the soleniod fire just once even if the trigger is held down. I have come up with a circuit here:

here is a pic of the insides of my gun:

This circuit works great, but I need to know if it is safe and or efficient. Is there a better easier way to achieve the same result? I do not know much about capacitors, is it bad to have them being charged for extended periods of time? Also, my AC adaptor say its output is 12 volts DC, but I measure 19 volts at the leads. Is this bad for my 16 volt cap? Should I find a real 12 volt power supply? And for my final question.....The capacitor I am using has barely enough charge to fire the soleniod. Is there any way to slighly increase the force of the soleniod without jumping up to the next size CAP? Maybe by adding a resistor or something. Anyway, thanks in advance for any suggestions!
