Just took delivery of a new P238 HD. When I got the pistol home, I of course began to look at it closely. It was filthy! Under the safety lever was a huge glob of dark grease/oil. I began to clean it and found the interior fouled with carbon. It took quite a while to clean it and a lot of q-tips and patches. I know Sig most likely test fires new pistols, but don't they clean them after? I'm wondering if my "New" pistol is "slightly used"? What are your thoughts and was your "new" Sig clean?
