Im wondering what Glock people prefer over the 2 models? I just got the 23 but I'm considering trading for a 27....Why? Because it is a tad bit smaller. But...I hear the 23 is good but, when you want to CC it is good to have the 27 with the 10 rounder's. Some people dont mind having a slightly larger gun (23) I do. One reason I wouldnt get the 27, I dont know if this is true. The 27 with a finger extension on the magazine is about the same size as a 23. I'm just looking for some advice or reasons why you'd prefer the 27 to the 23.
