Reclocking a CVA drum is a fool’s errand, the hammer must be reworked. Yet another reason to avoid cheap guns. Sorry I can’t be gentler with the harsh reality.
The drum appears to have been slightly over tightened. Bending the hammer will make the geometry between the hammer striking face and nipple even worse. If you can unscrew the drum... you can add a small washer shim behind it.

I am thinking I will have to heat and bend the hammer out a touch.
But, do you think the hammer can take the heat and bend, or break?
I can not remove the hammer from the lock, it is on there to stay. I have a cheap "Ethan Allen" that had a misaligned hammer like yours. I ended up grinding out the inside of the front of the hammer and then notching it. Now it fires every time and the geometry is perfect. Bending it is going to change the angle of the striking surface.
Being the fool that I am, I would get my 6" adjustable wrench out, place it onto the drum (with the nipple still installed), snug its jaws up against the outside of the drum and rotate the drum about 3 degrees counterclockwise.
That would align the nipple with the hammer and such a small movement would not appreciably loosen the drum.
Simple fix for a simple problem and it doesn't envolve doing something that could break the hammer.
