I have 4 of these mags and a couple of them simply will not hold 10 rounds. 9 go in pretty tight and when I try and put the 10th round in it goes like half like the spring is all the way compressed. One of them is a year old and gets used weekly. It feels like it bottoms out solidly and if I force the last one Im afraid it will get stuck. I guess if it does I could just pop the bottom plate off and drop out the spring. When these mags were brand new they had some sporadic feed issues so I have already stretched the feed lips a small amount so I probably cant do much more there.

My question is has anyone else run into this and what was your solution. I dont recall where I got them from so I cant return them.
