If you have not handled a Glock 30SF I would suggest it. The reason I bought mine is it feels great in my hand. Most of the other Glock models felt like I was holding a big brick. As far as how you carry. Carry how you feel most comfortable. I also have open carried for a little over 2 years and it feels natural to me .I open carry a Ruger SR1911 5" for about 2 years now. Been leaning towards downsizing to glock 30/30s when i decide which is best choice for me.
