SDM fabricating makes gold/brass bead pinned front sights. Measure the height of the existing sight.
Adios,

SDM does make a gold bead front sight, but be aware that the 929 sight ramp length is shorter than standard sights. So, the sight is longer than the available space on the gun and will hang toward the rear.
Gold Bead and Tactical Target
The PC model should have the interchangeable sight system that just snaps in and out.
