Even though you have been attentive to your grip, I bet you are pressing on the mag release somewhat. Did you replace the "spring" (wire) when you replaced the magazine release? It's not an easy part to replace.

Interesting.

Well I shot it today and it shoots flawlessly. Absolutely perfect for about maybe 100 rounds in a row. Magazine stayed in, no light strikes. This is the first time I have ever shot this gun in a range session of ~100 rounds and not had at least one light strike or at least one time that it didn't lock the slide open or release the magazine after the last round.

Also the original barrel had gotten a teensy bit of peening on it, and I recall I did find a burr forming on the left edge of the feed ramp during breakin and I buffed it off with a stone. That's the interface with the magazine follower. So maybe it was the mag follower, the barrel, or both, causing the problem. However it shoots great now.

Couple more range trips before I am fully confident in it, but this was a really good sign.

So I sent my Kahr CW9 back after about 500 rounds, when it had developed a nasty habit of light strikes on 50% or more rounds. I sent it to Kahr and in less than 2 weeks it was back home. Came in today.

Curiously they replaced the magazine follower and the barrel ???

Range trip today to confirm it's fixed. More later.
