Honestly, if it still shoots left I might just file the right side of the ramp a little.
Why do that? Why let them get away with it? They made a sub-par gun, they refused to fix it. Your solution would take one more “unadulterated” gun off the secondary market, meaning (1) S&W is that little bit more likely to sell another new sub-par gun and (2) you’ll have a gun that’s still “wrong” but also now filed on.
Make them make it right.
