Okay. I'm hoping for a very simple thread. As I'm sure most of you know many Glocks will accept larger capacity magazines that were not specifically designed for that model. An example would be using the Glock 23 magazine in the Glock 27. Here is my question: Do you feel that the extra length and weight of the larger capacity mag would affect your shooting in a self defense situation? The reason I'm asking relates to a recent range trip with my G27 and my new G23. I wanted to try out the new gun and I also wanted to make sure the extended mags would feed reliably in the smaller pistol. I had no reliability problems, but I wasn't really comfortable with the altered feel of the smaller weapon. Have any of you tried it long term? Is it a feel you eventually adapted to? I intend to continue carrying the 27 with the magazine that came with it. What I want to know is if I should waste the ammo trying to overcome the different feel of the extended mags, or is it something that isn't going to go away. Thanks.
