Thoughts on a model 27 imperfect trigger job.

[Fencer]

Hello all. I was hoping to get some thoughts and advice on a small issue I have on my model 27-2. Some time ago I pulled it apart and replaced some worn parts (spring kit, over-sized arm, over-sized cylinder stop) to tighten it back up after a hard life of use before I got it.

I also did a polish job on all the internal wear surfaces. I was very happy with the smoothness of the action and the crisp break of the single action trigger, although it was very light.

Now after about a 1000 rounds or so, about half full power, the single action trigger break is light enough that I am a little uncomfortable with it. It will also not stay locked if you push hard on the hammer anymore.

Is there a way to reshape the hammer or trigger seer, or should I just replace one or the other? Thanks in advance for any advice!

With all due respect, just from the nature of your questions, and the gun's problem, suggests you should not fire the weapon until a competent gunsmith fixes it. One of the red flags on a revolver is cocking it, pushing the hammer & hammer moving off the cocked position, etc.

In Smith & Wesson revolvers the hammer and trigger are made from a relatively soft steel that does well at absorbing shock. The surface is then case hardened to resist wear.

If you "polish" these parts to the point where you thin or go through the hardened skin to the softer metal underneath they will wear quickly.

If this is what you've done the only satisfactory solution is to replace the affected parts.

If there is a gunsmith in your area who is qualified to work on Smith & Wesson revolvers (not all are) I would take the revolver to him. If not, I would return the gun to the factory and hope for the best. It will not be fixed under warrantee.

As Fuff says--if the parts were over polished you are most likely out of luck. If not then there is a way and I believe it is described and shown in Kuhnhausen's book on S&W revolvers. It involves a 6 inch fine stone and Kuhnhausen shows how to obtain the proper angles to increase/decrease pull weight. Sorry I can't provide you a link showing this. Maybe a search would find one.

Yes, but it presumes someone hasn't "polished" and rounded off the edges on the hammer's notch.

And it's possible, up to a point, to dress the angle on the trigger, but if it is already down to soft metal the adjustment won't last long.
