Thanks Tom.
I was thinking I’d have to shorten the TIR holder… Until I read ReManG’s post…
So it does fit, and with no cutting! Thanks ReManG, also were you able to screw the bezel all the way on? So the O-ring sitting behind does it seal up back there?
You’re not using the glass over the TIR correct? The math does work out 12.6mm minus 9.1mm = 3.7mm and that O-ring looks pretty thick in the photos, so I’m assuming about 3-4mm total for ditching the glass and O-ring, sounds about right.
If these fit with no modification it would be cool because you could change beam patterns by swapping out the TIR’s, I already have some 15 degree ones from fasttech, I’m going to get some 60 and 10 degree to try, in addition to the 45.
Here’s the different shops I’m looking at the 45 degree flood optic (I guess they would pretty much be the same part?)

Fasttech lists 12.6mm height and the others show 13mm.

The ones I currently have that I could try (I bought for the Convoy S2+ and S6) are 15 degree from Fasttech, they measure 12.68mm height. The look exactly like the 10 degree from IOS, looks like I could file the outer rim of the holder where it overhangs, and gain around 1.5mm.
Apparently though it’s not to hard to reduce the height of one of these, see the photo tutorial in post #19 of this thread : Have a Convoy S3 and hate the beam pattern? Here's how to fix it.
