Yes. I had the CDPII Pro for a year or so. I couldn’t seat an 8 round mag while the slide was locked. I had to load 7. I don’t think it’s the mag, this happened with Chip McCormick mags as well.
Dump the Kimber. I sent mine back to NY three times to get it “fixed”. On the third time they replaced the slide, it still wouldn’t function for spit.
