Yankee, I'm a huge fan of the Kahrs having owned two perfect PM9's, its the only pistol I've bought, sold, and bought another one.
The CM9 is very hard to beat, and its low price is just icing.
The PPS would be my second choice for 9mm carry.
The Glock 26/27 are more than just a little bulkier/heavier - they're akin to a brick compared to the smaller Kahrs. I have a G27 but rarely carry it despite liking it very much.
