I have a Wilson Tactical that I keep in my nightstand in which I keep one Glaser in the pipe, 5 in the Wilson mag, and 3 Hornady HPs bringing up the rear. In getting ready to go to the range tomorrow, I'm unloading the pistol and realize that the mag isn't engaging and it's falling out without depressing the release. When I remove 2 bullets from the mag, it seems to engage okay. Is this a mag problem or a pistol problem? Please tell me it's a mag problem!
