It sounds to me like your magazines are not seating fully/properly.
That is what it sounds like to me also.
You say you don't have a problem when you hold the magazine release button in while you insert a magazine. I have a couple of 1911s that work better for me if I do that also.
Sometimes you THINK the magazine is seated but it is not.
If you have any doubt, try pulling down on the magazine after you insert it.
If it is really seated, it won't pull loose.
