I decided the dent in the bottom of the magazine well bothered me just too much, so I decided to make an attempt to pound it out the best I could. But I couldn't figure out how to remove the follower and spring. The Model 8 instructions about depressing the follower and tilting it from right to left to lift it out the top of the magazine was not working so well for me, until I figured out the "right and left" was the short way, not the long way. It went back together much more easily. And yes, I oriented the spring correctly.
Anyway, I used a 6" long 1/4" socket extension as a tool, both ends. I hammered out most of the dent (using a very light hammer) in just a couple of minutes. Not perfect, but not nearly as objectionable as it was. A good body man could probably do it a lot better.
