HUDSON — The couple was arguing about 2:30 a.m. Tuesday when the fight turned physical, deputies said.
Then Paul Dombrosky went into the bedroom of their home at 12709 Saulston Place and retrieved his .40 caliber Glock 27 handgun.
Dombrosky, 42, returned to the living room and pointed the gun at Ashley Frost, 22, who asked him not to shoot her, according to a Pasco County Sheriff's Office report. Dombrosky fired, deputies said, hitting Frost in her right hip.
Frost was taken to a local hospital, where she is being treated for nonlife-threatening injuries.
Dombrosky was charged with attempted murder and was booked at the Land O'Lakes jail.
Authorities did not say what the argument was about.
The couple has been dating about a year and a half.
