glock 19c sights?

[Turbomrdeuce]

hey guys i bought my wife a 3rd gen glock 19c. Gun shot great initially, i just went up to oregon to visit my father in law and brought the guns and we went shooting. Her sights are off, i thought maybe i was rusty so i grabbed my sig p226 .40cal (glock is 9mm) and i was on the money. Glock is shooting high..... Are the sights adjustable and how are they adjusted if they are? Thanks

The factory rear sites are available in several heights to correct up or down.
