The Kahr is nice. I have shot one, but don't own one in .40. I do own a Glock 27 that I have carried every day for several years. It is a little wider than the Kahr, but conceals and carries very easily in an IWB hoster. It is also very reliable. In fact, I have never had a stoppage or failure to feed. It is also very easy to feild strip and maintain. Lots of accessories, sights, and holster options for glocks out there as well.
