I would disassemble and clean it before you shoot it. Then use a little oil (Rim oil, Hoppes, ect.) in the areas specified in the manual. I bought a NEOS about a year ago and really like it. I seem to have more trouble with too much oil rather than just a drop or two. I would also get a bore snake, that barrel will tear your hand up running a rod through it.
Last but not least, take an NRA handgun class.
Good luck and be safe.
