The same P&S that was shouting about #allthelumens and #science?
I personally don't see too much point in the OKW on a pistol light for most folks; the PLH v2 is what I put on my rifles to begin with, but could certainly be of use with its compromise flood/throw specs. Yes, you can umbrella and bounce and all that shit with the OKW, but meh, why not just go for some floodier stuff on a pistol to begin with?
