He said that on the 6th or 7th shot when the slide recoils if there was not enough tension on that spring the slide lock could flip up and lock the slide back.
The Kimbers have a spring on the slide lock? I don't think so, unless you are referring to the mag spring and I thought the Wilson's were new??
Either you got the info wrong or you need a new gunsmith!
This is why I use Tripp Research Cobra Mags:
This is a Wilson Combat ETM on top, and a Tripp Cobra mag with the long skirt steel/polymer hybrid follower on the bottom.
The second reason the Tripp Cobra mags are superior is the machined feed lips. The Cobra is on the left and the Wilson ETM on the right. The metal forming is night and day. Notice how the round sits squarely back in the mag on the Cobra.
The feed lips are longer on the Cobra holding the round longer as it's stripped and moves forward to battery. The other arrow shows how the Tripp forming is much more fluid than the Wilson.
From a shooter's viewpoint, I find the Tripp Research mags to be works of art and from my experience have verified, in this case, function follows form!
From an engineer's viewpoint, I have found no other 1911 magazine that comes close to the quality and function of the Tripp Research Cobra mag.
Are they expensive? What price do you value your life? In my carry Colt you will only find a Cobra mag!
Why would you even consider putting a $14 mag in a $1,200 carry piece?
