I feel a little guilty, I have approached my new guns much the same as AR, I buy, I inspect and I shoot. The reason being is I have not seen heavy grease, oil or any other lube that looked excessive. I also believe that most all of my S&W guns are test fired, then directly packaged for sale. They are not cleaned, they are not lubed with anything for storage or shipping, they are fired and sold. I want to make sure before I mess with that gun, it functions correctly. I don't want to be one of the newbies that comes on this site complaining about S&W and their quality control going down the tubes because their new gun doesn't shoot or function correctly. (Not referring to the OP here) Because while learning about their new gun they screwed something up. I want to make sure my new gun functions correctly out of the box. That's me, that's my perception and my expectations. I'm not sure, but does it say in the factory manual for our guns, we must break down and clean before firing, I am referring to my M&P's... Once I've made my range trip and all works as advertized, I'm all over cleaning .... usually... although lately, I have been kinda lax in that area. What a surprise, they still continue to shoot and function...
