3906 trigger help please.

[dsanders3906]

Ok, so the deal is my 3906 has what I can only describe as "play in it" When in single action, the trigger will dangle a little. It does functions fine. Never any problems. However I know that it is not suppose to be this way.
If I field strip the firearm, and apply slight pressure to the triggers group area,
right in front of the trigger play spring, the problem is solved.
What would you guys say is the problem?
I do not want to send it back to smith for what appears to be a simple problem. just asking for advice due to curiosity. I play on doing a tune up, just want to know what the problem is before my spring kit/ tune up kit arrives. I also feel that I might have missed something and a tune up will not help, so please help.
1) trigger play spring
2) trigger plunger spring
3) replace all the springs due to someone not reading the post and telling me what I am not asking.
4) something else I missed

I had a problem with my 4566 that sounds similar to yours. It seemed like in single action the trigger would dangle a bit, then click before beginning trigger take up. It then functioned ok in single action after this take up. I took it to the local gunsmith. He said the trigger was actually rubbing against another part that had come loose and now the trigger has a great tight feel without a dangle and click.
Even though I envy those who know the inner workings of my pistol,
I know enough to know I don't know anything about the innards of my pistol so I'll let him examine it first!

Against my better judgment I decided to strip the frame and take a gander at her innards. Pretty confident that I now know how to curse in languages that have been " dead" for centuries( a side effect of reassembly) but I also identified the problem as the trigger plunger spring. Either way, it was a fun experience and, I can confidently say I can fully dissemble a 39 series ( or most 3rd gens). (I did make sure that I used proper tools and was very careful-following instructions to the "T"- knowing that this is a firearm and dangerous things can happen with neglect) At any rate, I will replace all the spring with the above mentioned tune up kit, as well as the trigger play spring. $18 dollar in parts and might as well change the wires if changing the plugs right?

Dsanders; Your on the right track. Trigger play spring on the trigger bow. Easy fix; detail strip pistol until trigger bow is in your hand, insert trigger back into trigger bow to see how play spring bears against back of trigger hooks to take up slack of fit. Then all you need to do is dehead the small rivet holding the flat take trigger play spring, remove spring and drive remnants of rivet out of trigger bow, place new play spring on bow, insert new rivet, back up head of rivet with large punch locked in vise, and peen hollow end of rivet down to hold new spring. Fixed. Re-assemble and you are good to go. Now, sometimes people have tried to bend the "ears"(old style) or tab(new style w/ one tab instead of "ears") of the spring forward to take up the slack an older gun's spring has, but in my experience, the old spring is usually sacked, and bending the tab does not hold. Best bet is to replace spring. Better fix, too. Especially if the take up spring is the old style. New style spring holds up better over time. This is the 1 very minor aggravation I find in older S&W metal frame auto's; all of them usually suffer this spring failure at sometime in their lives. Pistol will function just fine w/ or w/o spring, just w/o or loose spring you will experience trigger wiggle or flop in single action mode. I keep several springs and rivets around just for this reason.

Thanks. Least I know that I am on the right track
