It depends on the caliber and the specific gun. I generally like Gold Dots the best.
.25 auto
-- 50 gr. FMJ from any quality manufacturer
.380 auto
-- 90 gr. FMJ from any quality manufacturer except flat nose ammo (WWB) which does not feed well in one of my pistols
.38 spl (standard pressure)
-- 125 gr. +P Gold Dot (in snubbies); VERY LIMITED AMOUNT in my standard pressure guns
-- 148 gr. lead wadcutter
.38 spl. +P
-- 135 gr. +P for short barrel for my snubbies
-- 158 gr. +p Remington LSWCHP for four inch barrels and longer
-- 158 gr. +P Gold Dots for 4" or longer barrels (old stock of newly manufactured ammo from Georgia Arms)
.357 magnum
-- 125 gr. or 158 gr. Gold Dots depending on how sights on gun are regulated
-- Any 158 gr. JHP from a quality manufacturer. You have to work pretty hard to screw this one up.
9mm
-- 124 gr. +P Gold Dots in my Kahr CM9 (three inch barrel)
-- 124 gr. standard or +P Gold Dots in all my other 9mms (longer than 3" barrel)
