Hi there fvf,
Yes, the trigger pin does not sit flush on both sides of the frame. There is a reason for that.
Here is a link for disassembly instructions:

You will have to remove the trigger pin, pull the entire assembly from the pistol, the trigger lifter will drop off (don't worry, its designed that way). Place the trigger assembly on a board with a hole bored into it to recieve the pin and knock the pin out of the trigger. The magazine safety and spring will fly out of the trigger. Keep an eye out for it in case you decide you need to reinstall it again.
The pin at the front the trigger is to retain the trigger return spring. I replaced my trigger return spring with a C&S x-tra power return spring. Some folks simply remove the spring and bend down the "tail" of the spring 1/4" down using pliers to get more tension on the spring for a more positive trigger return.
When you reinstall the spring, its time to put everything back together. Put the trigger bar back on the trigger and under the spring. When you reinstall the trigger, gently move the assembly back up and into the frame the same way you removed it. Don't get upset if the trigger lifter falls off a couple of times until you get it right.
Then, using a punch as a slave pin, hold the trigger in place and reinstall the trigger pin back into the frame. The groove or notch in the pin must lay in line with the spring or your trigger will not work when you shoot the gun. Remember I said that there is reason the pin was offset?
It's easier to do than I have described and pictures would help!
