I have a K frame that I haven't shot in years that I fired a few times yesterday. I say a few times because single action it would have a fail-to-fire one round (or two) per cylinder, and occasionally DA too.

I'm looking on the Wolff Spring website, I know cut coils off a mainspring can cause light priner strikes, but what else should I order to get this stainless K frame back to 100% reliability?

Thanks for your opinions and your help.

K frames have flat main springs. (at least the ones I worked on)

Take the spring out of the gun and tap it flat on the table, then put it back in. That should give the spring more tension. Make sure the strain screw is tightened all the way up.

If that don't work, replace the strain screw or try another spring.

There is a way to test hammer tension, look in the faq to weigh the hammer.
 
Sorry, I was sitting here looking at a K frame FLAT mainspring on the Wolff website when I was typing that and thinking of a J frame.

Screw is all the way in, checked that at the range table. I'll try the mainspring straightening suggestion.

I'd thought that the trigger pull was light from the begining. And the mainspring was the thing I'd considered ordering. Everything else seems OK, no push off or 'buggered" sideplate screws to indicate a kitchen table gunsmith had been in it.

Factory recommended (armorer school) adjustment for taking some tension off of the flat hammer spring is to file the strain screw then reinstall tight. It is possible your screw has been altered in this way. I have seen all sorts of mischief done to these springs, including replacement with lighter ones, deliberately bending them and grinding the spring on both sides to make it thinner. I would recommend you check your strain screw against one you know to be unmodified and see if yours is shorter by a significant amount. A new factory spring AND strain screw should be the most you will need I think.
