Can one of you all talk to me about over insertion? I had not heard this term before, but I feel that it is relevant to my recent situation. I have a DW valor blue in 9mm. I have tried a few mags and bought a Wilson ETM. I had no malfunctions, but the front/top of the metal on the Wilson mag now has a dent in it. I have to believe that my feed ramp hit it. I now do not want to use the mag for fear that I will damage my feed ramp. Did I do this by over inserting the mag or does the Wilson just not fit my gun? Thanks for any insight. Learning.
