I just bough a CW45 new yesterday and if you manualy cycle rounds through the slide won't go all the way forward and then when you bump the slide forward the round will get stuck in the chamber and is the slide won't move more the than 3/8 inch unless you keep on jerking it to get it out. when firing the gun after it cycles you have to bump the slide forward 90% of the time out of the 25 rounds I fired before I gave up. I did use moly paste on the slide rails which didn't help. the gun only came with mag and I used RAM 230gr FMJ and can try again with different ammo and mag when i get a chance. Also after only 25rds the part of the frame closest to the barrel melted a little bit which is also cause for concern.
