Hey everyone!! I am wondering for those who carry with a backpack or sling, what do you use? I have seen such as Vertex but the price is a bit much for something such as a backpack. I won't be taking it out camping or such. Just for when I go to gym, or for any reason I won't be able to use my holster. I'm not wanting to spend crazy money. But I would like something nice to have on my back. The more discreet, the better. Preferably with a compartment for my G2C. Thanks in advance, as always!
