Should you clean a new gun before shooting?
New gun owner here. I'm wondering if newly-purchased firearms should be cleaned and oiled before taking to the range, or if it's fine/safe to fire them as is and then clean + oil afterward.
If indeed it should be serviced out of the box before using, to what extent should it be disassembled, cleaned and oiled? I have a pump action shotgun, a revolver and a glock in case that makes a difference.
Is there a higher likelihood of malfunction or other issues if you don't clean it out of the box?
Thanks.
