Yes, a heavier bullet has been going higher for my new CZ during it’s break in period. I’ve been shooting any 9mm stuff that I can get my hands on and shooting at 10 yards. The 115’s go low, the 124’s go a bit higher and the 147’s go point of aim. Not that there won’t be a new set of better sights in my future, but for now it is mostly finding 115’s and living with 3” low.
