Spent a few hours today working on my 625 JM and tuning up the trigger. I bought the Jerry Miculek S&W Revolver Spring Kit that he sells off his website Bang, Inc. and decided to follow some of his instructions on the Trigger Job DVD to smoothen the trigger action and associated parts.
I know this sounds dangerous and amateurish, yes indeed it is but what better way to learn about the gun than to try it yourself? If I screw up, then I’ll send the gun to Carmoney or Jerry to get it fixed. Consider it an educational fee 
Here’s my original Trigger pull weight :
Here are all the pieces that I worked on :
and after fixing the action, polishing the internals and reducing the mainspring weight :
the action is much smoother, but I am still very skeptical. It feels like the firing pin will not be able to strike the primer properly. I have loaded all my revolver rounds with Federal Primers and seated each one very well but I still do need to test this out on the range, best way to find out.
What’s good is if it doesn’t work, I’ll just tighten the strain screw a little bit and test it again.
*UPDATE* Here is the 3 part series of my gunsmithing adventure!
Sounds excellent. I am going to try this. I have Jerry’s spring kit and his DVD. I have also done 6 Gene Shuey trigger jobs on my Glocks. Polishing s/b no problem as should India stoning . Thanks for the excellent posting. Buddhas
np Oz! Thanks for stopping by. The hardest part for me about the whole thing is sliding the spring back into the rebound slide. If only I had the proper tool, I ended up using a larger flat head screwdriver. rough but it worked.
A small Philips screwdriver works better. The point prevents slipping off the spring and the frame pin can slide up into the cross recess easily.
