Just got back from the range with the CW9. Put 170 rounds of UMC, Rem. Green Box, and Win SXTs through it for break-in. Had four of the Green Box fail to fire and all had good primer strikes, so I attribute that to the ammo. No other problems of any kind with any of the ammo. Had to get used to the sights and learn to keep so much finger out of the trigger, but when I did, the pistol was extremely accurate. Dead on at 7 yards with the UMC and Remington. Very easy to handle and the recoil was extremely light compared to my Kel-Tec P11. Only shot at 5 and 7 yards since I was just trying to get the requisite break-in rounds through it. I now fully trust it and it will be carried. Need a good IWB for it, but right now it is in a Fobus paddle made for a 1911 and fits pretty good.
