Assimilation is inevitable.

Buy me a G19 and I will use/carry it. I don't have a problem with Glocks (other than they are wrong). I'll generally tell people that's what they should look at..... or a wheel gun depending on the circumstance. They are a fine gun if all you are concerned about is utility. They just aren't that high on my list.
