Just shy of 11 months. M&P 45 with Ti-rant 45. Let me edit that to say 10 months and change. And yes, Dawson Precision adjustable night sights do clear the can.
Congrats, I have a Tirant 45 and its deffinetly one of my top favorites, probably right behind my element. I pretty much only shoot mine wet on a Glock 21 and its wesome.
