I'm having the same issue. I installed red dots on many of my other firearms because of the same issue. Even three dots without tritium or FO cause problems now. I don't want to alter the slide on this gun though, so I'm looking for a replacement front sight.

I wish the Custom Shop would have offered options for the front post or sight. It looks like Brownell's, and numerous other aftermarket suppliers carries sights that'll fit. I'm hoping to hear something back here before I make a purchase.
