If all you're asking is what US wrench is 33.3mm -it's a 1-5/16"
33mm =1.311
1-5/16 = 1.3125"
On the other hand, if that's not your question:
The CB2BA adapts to the CB muzzle device system; not seeing how that can be used in any with a 3 lug system, and CB brakes are not made in pistol calibers.
The FLY 45 booster basket system adapts to standard HUB; that would seem to let you adapt just about anything.
Suggest contacting TBAC; they have always been lightning fast in answering my questions.
