Can the threaded insert be changed from 1/2X28 to the 13.5X1?   Will Surefire sell the part?

Yes and yes. Call them up.

Right now it's my understanding Surefire is allocating all the pistons they have on hand for filling orders, and they are not yet available for purchase separately

Just give it time, and they will be available

Most online vendors are giving you the option of 1/2x28 or 13.5x1 LH with your purchase

Local dealer has one that he could sell me for as good as I can find it online, but all he has is the 1/2X28.  Thought it might be worth it to get the paperwork going and get a different insert while I wait.    I want metric to fit a Sig factory barrel, but have a Beretta with the 1/2X28...

If you like the can, I would not hesitate to go ahead and get the ball rolling.

By the time your F4 is approved, pistons will most likely be available...
