I know there's a thread on here somewhere with thread sizes for both ends. However (unless I overlooked it) I didn't see any for Surefire P series or G series, hence this post...

G series measured out to 22mm head and 18mm tail, both at 18tpi.

P series measured out to 28.3(!)mm head at 20tpi, and a 22mm 18tpi tail.

Do these measurements jive with what others are getting? The thread pitch comes out crazy in metric, I think it's something like 1.44 at 18tpi...which is the reason for the mixed measurements I used.
