S&W mod 19-3 trigger hangs up

[ACES&8S]

S&W model 19-3 trigger still hangs up on return after I replaced the main spring & rebound
spring , I also honed an obvious burr from the frame below & in front of the rebound slide.
After I did all this it performed perfectly the first 40 rounds , then the trigger began doing like
it did before, like every 4 rounds with 357 or 38 it doesn`t return to battery. It almost makes it
back & stops. I can easily push it forward into the ready position.
The revolver is in very good condition considering it hasn`t been used in years.
Cleaned it completely.
Any ideas out there?

Is the trigger stud bent? Is the cylinder stop spring in correctly?

Thanks it works great now. I ran 50 rounds thru it with no hang ups.
The studs are ok & the cylinder stop spring only had a slight kink in it but it must have been enough to cause
the trigger to hang back.
I always have extra S&W revolver parts on hand for such things so it pays off.
Thanks again.
