Ok, I put another 250 rds through the gun tonight. I love this little bastard. 25 of those rounds were single rounds fired with the magazine removed. The steps taken are as follows:

1.) I began as if I were going to remove the safety levers. Once the two pins were removed from the frame, I removed it from the grip.

2.) I pushed the hammer pin out (mine was easily removed with my fingers), and removed the hammer. **CAUTION** This is where the trigger connector fell out and bounced under our kitchen cabinet.**CAUTION**
The connector is just in front of the hammer on the inside, right edge of the frame as the weapon is pointing away from you. It is a flat vertical bar that rides the trigger bar and is retained by the hammer pin. Go ahead and remove it so as not to lose it as it will fall out on it's own. Pay attention to it's orientation prior to removal and return it accordingly once completed.

3.) I then located the magazine disconnect safety lever. It is retained by the pin straight below the location for the hammer pin. This one was tight and I had to use the punch. The lever mounts to the right side of the frame. I drifted the pin in from the right side only far enough to clear the lever itself. The lever widens on the back half and protrudes into the side of the frame. To account for this:

4.) I loosened the two screws on the left side of the frame only far enough to provide enough space to clear the lever from it's recessed position. Be careful as to not dislodge the sear spring mounted in the bottom rear of the frame. Be cautious working the screws, they are soft so use a properly fitting phillips bit. In the end, I removed the lever and a flat spring. Once I lost the connector and halted the operation to find it, I found a small coil spring similar to the sear spring. I loosened everything back up and attempted to find where it came from but no joy. Once I liberated the connector and put everything together, it all worked. I cannot say for sure that the coil spring came out with the lever. Sorry, but I simply did not see where it came from. I attempted to contact S&W and asked about an exploded diagram of the gun and, of course; they declined to share. Everything does work and the gun runs flawlessly without it.

Once the components were removed, I reversed the order and proceeded to performing a proper functions check.

This was not a shining moment for me. I envisioned it going a bit smoother than this. I almost decided not to share this info as it is not quite the quality that I was hoping for, but I decided that maybe this info could help get someone else started or help them to make the decision to just leave it alone. If you do not agree with performing this procedure, please feel free not to use it. The included information is simply offered as a chronicle of my experience with performing this modification and is in no way to be interpreted as expert or technical advice in nature. It is as it has been presented, information only.

I apologize that I do not have pictures to go along with my narrative. Once I got to the point that I lost a part, I was more worried about getting my son's new gun running again than documenting my misery. I hope that this will help someone else here. Also, I am optimistic to hear from someone about whether the small coil spring I found did indeed belong to this assembly. Happy wrenching men.

Thank you Dog1 for your guidance.

After studying some of y'all's pics, I realized that my trigger does not stay articulated forward far enough to engage the built in safety. I over-articulated it once while trying to get a better hand hold on the frame to reinstall a component. This may be where my extra spring belongs. Every other feature works (the ones that I haven't disabled anyway). So, I think that it stands to reason that it could belong here.

With S&W declining to share an exploded diagram, can someone help me out here? Is there a coil spring behind that trigger safety to keep it articulated forward? If so, how does it fit in there? I can't see down in there and I don't want to knock the pins out of the frame again to get to it if I don't have to. This little guy is kicking my ass so far. Thank you in advance for your help.
