I have the Solo CDP and love it. I have not had one failure of any kind so far. I have stuck with 124 grain and above ammo. I waited a year before purchasing the Solo because of all the early problems. My CDP was just under $1000. It has night sights and laser grips. The carry melt is wll done and the checkering on the front and back straps of the grip is nice. I think the CDP is certainly worth the extra expense over the standard model.
I have to admit the P938 is tempting though. I might have to have one of those too!
