If I drill the air transfer port out in the receiver of my 357 Bulldog,do have to drill the transfer hole in the barrel too? Pitbull air says I can drill the transfer port hole with a letter M(.295")But doesn't mention anything about drilling the barrel.

Well if the ports do not match then you are limited to the flow of the smallest one. All ports valve, transfer port and barrel must be the same size for the flow to not be restricted.

I drilled my barrel port to match the transfer port.
Make sure to be careful and de bur it.
I have a lathe so I machined a snug aluminum plug to fit the barrel and when I drilled the port I put the aluminum plug in to drill through.
The bit left the barrel port almost 100% burr free.
