I have not had trouble with any magazine except Pachmayr. The absolute best I have used are Mag Paks (SP?), but they are not available anymore as far as I know.
Otherwise I have found the
SA, Wilson, Colt, McCormick, GI, and a couple of others all are reliable. I have not found one better than the others, and have had a couple of Wilson base pads break and dump my ammo.
I have not tried Tripp, but have used their repair kits, and they work well. I have not found that a particular brand maq is a miracle if a gun is malfunctioning.
