You need to clean the gun before you shoot it. I had trouble removing the takedown pin. I resorted to tapping it out with a punch and hammer.
The slide release spring is easy to damage. You need to replace the slide release spring so that the spring sits on top of the slide release. I damaged the spring before I even shot the pistol. When the spring is damaged, it shoots in one-shot mode. You have to release the slide after each shot if the slide release spring is not on top of the slide release. My first 200 rounds with the CW40 was basically in one-shot mode.
I repaired the slide release spring. I then shot 50 rounds of Winchester white box from Walmart. The slide still locked open twice when the magazine was not yet empty. The CW40 also jammed two or three times when loading a new magazine.
I am not a bad shot, but I often could not hit a 13"x13" target at 25 feet with my CW40. During the same shooting session, I was getting a 3" to 4" group with my Ruger SR9c. Maybe it was the CW40, maybe it was the ammo, but it wasn't me.
In the manual for the pistol, they say the that you should provide resistance to the pistol, not act as a shock absorber. The gun seems to be better behaved when you hold it loosely. Why should I have to adjust my grip to shoot the CW40? Also, they CW40 seemed to behave better with a 165-gr. target round than a 180-gr. defensive round. Weird.
I am an average size guy. This pistol almost seems too small in my hands. There's little room for my left thumb on the frame (I shoot righty). Again, I don't want to adjust my grip drastically to shoot the CW40.
I am going to try different ammo. I am going to call Kahr to get some suggestions. However, I have no confidence in this weapon for concealed carry.
