Over the course of time, I have switched completely over to the Tripps and now have a number of Cobra mags. I also bought four Tripp 7rd. mag rebuild kits and rebuilt two Kimber and two CMC mags with Tripp innards as well. They all function like champs in both of my 1911's.
If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen. ― Samuel Adams
