Hi folks. I just picked up my first handgun/glock and I have a few questions about it. When I was at the store the guy told me 3 places (i think) that I should lubricate before I shoot the gun for the first time but I can't seem to remember what he told me to use or where exactly on the gun he told me to and to lubricate. If someone could explain or point me in the right direction I'd appreciate it. Maybe use the Hoppe's? Can't remember. Second. I noticed when I got home that the right side of my front sight is a tad higher than the left side. It bothers me a little bit but I'm sure it's not a big deal. My question is whether I should call the shop I purchased the gun from before shooting it and if this is a common new gun problem that can be fixed easily. Any info appreciated. Thanks!
