“the Kimber mags are trash“
That’s odd. We own two Kimber 1911s and a dozen Kimber magazines for them. Not one single failure due to the magazines in over 2 years.
Not one.
They ain’t cheap at $50 a piece, but they’ve been worth every dime to us.

I'm pretty hard on mags, in training and competition (frequent drops to hard ground).
Keep a watch on the baseplates for spreading. If you use pads it will be harder to spot.
