Took my Kahr MK40 and my Kimber UC 45 to the range and I noticed the Kahr's +1 mag (6 rds of 40) is almost exactly as tall as my Kimber's normal mag (7 rds of 45)! Both are single stack.
How is this possible? I would think I'd get at least 1 more 40 round than a 45! The Kimber does have a steel follower vs the Kahr's plastic one. Do they really take up that much space? Or just poor design/springs on Kahr's part?
