Hey, guys! I picked up my first gun on Saturday, a Glock 21 OD. Now, question for the forum: it was a consignment purchase, so I know that the gun was test-fired by the store, but do you guys think I should give it a thorough cleaning before I take it to the range? I would reckon that they don't clean guns after they test fire them, but I could be wrong. Also, I matched up the serial through the sticky thread on this forum and the gun was made in 2005. This thing looks brand new. So, yeah, it's definitely been around a few years. I just want to make sure that if I need to clean it and prep it before I take it to the range -- that I do it. Thanks!
