You stopped stirring???
You have a standard 1911 with an 8 round ( plus one ) normal magazine fed system.
Tripps will work. 47D's will work. A lot of types will work. Or, I should say "should" work. Some weapons just don't like some types of magazines.
My Kimber won't feed my Nighthawk mags, but with everything else, it feeds just fine. You have to try them and see what works and what does not.
Obviously I wouldn't buy several hundred dollars worth of the same mags just because you like the name or the style. Buy one and see if it feeds correctly.
Chances are good that most high end mags will work great. But don't make them your carry mags until you run several dozen rounds through each mag without failure.
After all, it doesn't matter if you have an $8 magazine or a $50 magazine, if the damn thing doesn't feed the ammo into the chamber it doesn't matter who's name is on the buttpad.
