I have 3 CPX2's, waiting patiently for two trigger pull reduction kits (not the stroke kits).
They fit my ham sized hands pretty good. I don't think they are CC worthy for the most part, not because they are inexpensive, but because they wouldn't run steel cased Wolf polyformance reliably. That doesn't make them unreliable but it does likely make them picky. I haven't yet put any factory brass case or my own home-rolled through any of them, the snow is too deep to find and keep the brass.
I am looking forward to getting the new one however. I'm torn on the battery operated parts though, I don't shoot one particular gun often enough to keep batteries around for them. I just gave away my red dot because of that.
