The first thing I do is remove another strain screw from another S&W revolver and compare lengths. If longer (it won't be much) try it in your Governor.

Another way is to take a used primer, remove the anvil, and stick the cap on the end of the strain screw, install, and tighten all the way. Then shoot it. If the light striking goes away and you get ignition !00% of the time, request a new screw from S&W cust svcs, not the parts dept, they'll likely send you one free.

Or just leave the primer cap in place. You can also file the cap thinner and experiment so the trigger pull is no harder than it has to be.
