Had to send one of my SD40's in for a minor gritty slide action! I have 5 Smith pistols various models and all work perfectly with Butter like slide actions. With the exception of the last one a just purchased. Most folks probably would never have noticed. Its not like I need that particular pistol back right away! But, S&W has had it for over a month. They have a new computer system that evidently is not linked up properly with Fedx. I will be glad to have it back though.
