Just got my shield. Fine, fine gun. Everything is great, but the slide release is really stiff. From experience, will it loosen up? Other than that, the gun is classic S&W, put together about as good as it could be. Unlike many, I love the safety. Needs a little effort to engage it, but comes off with a sweep of the thumb. My first striker fired gun, so the safety is reassuring, at least for now. Going to run a box of ammo through it this afternoon.
