The original spec for the magazine was 7, newer magazines hold 8, but many still make 7 rd mags.
Just bought a new Custom CDP II. My first Kimber and it is wonderful! The Kimber site and instruction manual show magazine capacity at 7 rounds. The included mag was also 7 rounds. I bought a spare Kimber mag at the dealer and it's 8 rounds. So I tried it with the 8 round mag at the range and it worked fine. Any idea why Kimber would limit it to 7? I tried to search this topic and didn't find anything.
Thanks guys! Never would have guessed.
