SureFire 9P with Malkoff: What's the runtime on RCR123A?

[etc]

What kind of runtime can I expect from a SureFire 9P moded with Malkoff M60, with 3xRCR123A cells?

How much worse than using primaries?

Max voltage is 9V. If you used 3 x R123 it would go

I think you would want to use 2x 17500's in that application. The correct voltage range and way more capacity than RCR123.

Question,
What kind of runtime can you expect from 6P + M60?

On RCR123?

thats what I would do, either that or have a CPF machinist bore out the 9P for an 18500, but the added capacity of the 18 might not be worth the effort over the 17mm cell. But either way it capacity will be double that of an RCR123. I don't know if anyone has done that before on a 9P though.
