The weapon is dirty or needs de-greasing knowing taurus.I have a PT92 AF that after every other shot fails to completely go into battery. It almost completely goes back into battery and is extremely difficult to clear almost impossible. Anyone have any ideas why a new pistol would do this..
also possible weak or broken recoil spring, rough spot in slide rails or frame rails, thats where I would begin looking.
assuming that this is with factory ammo, if using reloads then first stop would be checking the reload and making sure they have been placed back into acceptable standards ( OAL, case dimensions) for new ammo.
sounds like a ammo issue just from your description, have you tried different brands of ammo?
