Does anybody here remember when their mags were new? The 3 mags that I have for my 34 were pretty tough when the last few rounds were loaded in. Now, they just slip in. That has to say something for springs wearing out. I too have a 33 rd mag (2 actually for the Kel-Tec Sub 2000 that I am on a waiting list for) and after leaving 25 rounds in it for 3 months (my nightstand gun is the 34 with the 33 mag) the last few bullets barely pop out when I cycle them out. They probably will feed all of the time, but I don't want to find out that they don't at just the wrong time. Yes, I believe that springs loose their "spring"! There, I said it. But from what I've seen, it's true. Go ahead, try loading a brand new mag next to your old one, you will notice a difference. And if springs don't wear out, you wouldn't!
