Hello. I have a 722 that will misfire when I shoot it double action. It always fires when shot single action(probably since the hammer stroke is longer when shot single action). When shot double action I will often times get one or two rounds that don't fire. The firing pin strike marks on the cases look pretty light on the ones that don't fire.
I did some researching on this topic a while back and most people recommended replacing the main spring. So I ordered a new main spring from EWK and installed that. Unforuntately it still has the problem. I have also thoroughly cleaned the thing(focusing on the hammer and firing pin areas) numerous times, but that doesn't seem to help either.
What else can I try?
Thanks!

Maybe you already tried this but did you try some different ammo ?
Also is possible gun may have had a trigger job and not a good one
if you know what I'm saying ?

Oh yes, forgot to mention that. I have tried three different brands of ammo, and they all do it. As far as the trigger goes, hard to say. It feels very similar to the 357, model 15 that I have.

Just a few thoughts. Have you had the firing pin "out" and cleaned the channel it rides in as well as the spring? Is the firing pin worn? Also how much end play in the cylinder do you have. Check and see if you are reaching full lockup in DA. Has the mainspring seat (the thing the grip screw threads into) backed out some? You may have already looked at all of this but just throwing out ideas. good luck.
