I've been a Glock guy from the start and I have a lot of reasons for choosing Glock.
My primary home defense gun is a Glock 22 and my Glock carry is a G27. .40 is my round of choice, but I have the 9mm conversion barrel for the G22 and plan to get a 9mm conversion for the G27.
I've always liked the way the Glock is so simple in design. Frost and I were talking about that a day or so ago.
From a design standpoint, they are easy to understand, easy to work on, easy to change parts, and quite plentiful. If you needed "repair parts" the Glock 9mm would be one of the most likely things you would come across.
I'm just curious, what is the tipping point that made you change from XD to Glock?
Good choice!
