I have a few requests for the XC1....
It resides on my CZ P-07 and I like it, with that said
-Make the momentary both up and down on both sides like the X300 and possibly constant on also. But at least make momentary work both ways, would love to rock one on an SBR'd 12 o'clock rail for HD.
-Squeeze another 50-100 lumens, if they can. At 200 it's just about perfect for pitch black HD but at my indoor range with incandescent dim lights I've noticed the flood of the XC1 tends to get washed out. This is an issue when I'm trying to practice momentary while pulling the trigger and I can't tell if I'm activating the light with certainty. Muscle memory and all that.
-Move the mounting screw back or something. We all know this is a G19 light and it may fit all the others, but honestly, not much smaller than a G19, and this light doesn't fit A LOT of pistols. That's an issue IMHO if Surefire is marketing this as their compact light, ideal for compact guns, to help with concealing...
But all in all, it's a good "GEN 1" effort and I hope they make some positive changes.
