I am looking for any feedback on the tightness of glock mags. When the last round is pushed into a glock mag it is really tight. And when the mag is full then it is equally hard to push into the gun, not that I can't get it seated, it just seems harder than necessary. I would think that glock would have added some extra space to fix that problem. Does any body have any ideas on this? I have been thinking about adding extra round extensions and just leaving one round out to add extra space, but I am open to any ideas. For now I am carrying 12 out of 13 in my 23.
