I came to some conclusions thanks to the people of this forum. I believe I will be sticking with Glocks for my future purchases for the sake of familiarity with their system and living on a budget. I would like to own some other types of handguns, but that just gives me something to look forward to when I have a better job and more disposable income. This also allows me to save for magazines and ammunition. I also think I will stick with the handgun calibers I currently own instead of expanding my caliber selection. This makes logistics easier. I have narrowed my next purchase to either a Glock 26, a Glock 27, or a Glock 17. Thank you all for your help, it is very much appreciated.
