Buy it, I would buy and 27 57 or 29 that functions for $500 especially a premodel 5 screw. I might hesitate if it was a model 28, but that is because I already have 5 of them, but, then if it was an early 5 screw pre 28 I would get it.

Unless it was beat to ****, it will be smoother than your brand new and shoot every bit as good.
