I like CZ75 pistols but I am sure the Glock 19 is the most size efficient service pistol made. I have spent a lot of money on high capacity magazines but no more. Therefore, the G19 gets my nod with 15 rounds vs 10 rounds.
When it comes to Glock Model 26/27 these little pistols are in a class by themselves. Yes, for me, they need a holster but for Stephen A. Camp he carries a Model 26 in his Dockers. My Model 27 will shoot with full sized Glocks and that isn't all bad. If you own a Model 27 you can, with minimum effort, have a 9mm, 357 Sig, and S&W 40.
