After years of swearing at my Presta pumps (including an old Silca with the head pictured above) I tried a Lezyne pump and haven't looked back. The reversible head screws onto the valve stem so that no matter how much you shake and twist, you never let air out until you unscrew the head. Perfection. I have the short frame pump too and have absolutely no problem hitting 120 with it, other than my hands get a little sore because it is pretty small.
