Allright, my wife just had a terrible experience at a local gunshop. She and her mom went while I was at work (which in itself is just WRONG anyway). The owner was terribly condescending and did nothing but sigh at her and was very snappy. Based on a lot of what she told me, I have half a mind to take her there with me and... Well... Anyway the other half of my mind is smarter and more thoughtful and long-suffering! Anyway, she was looking for some oil for lubing our M&P after cleaning (weapon shield is in the mail!) and the guy snapped at her saying she shouldn't ever use oil on polymer guns, the M&P specifically, but she should be using grease. Now I don't doubt his knowledge, he's a gunsmith and has a lot of experience, just no manners... She and I hadn't heard about using grease instead of oil. When we do use oil on our gun, we only apply it to the metal parts anyway. He was so rude he turned down a sale (didn't want to pay to process her debit card instead of her using cash) so we figure it wasn't him trying to get my wife to buy something more expensive... What do you think? Thank you.
