Alright just picked up my first piece, a gen 4 glock 19. Ive been shooting glocks for about 2 years now, so im still learning. However ive never actually owned a fire arm. Never had to clean one / field strip it / lube it up, any of it. I know i should clean it just about after every range session. So just looking for some basic tips or advice, maybe some pics. Appreciate any kind of tips i can get. I am taking some basic firearm classes in 2 weeks and dont wanna look like an idiot.
