"No need to by an expensive 9mm loader. This one works perfectly. I got it for my SD9 and it is great!"
"Although Glock provides you with one magazine loader, we all know that either 1) You will lose it at the range, 2) The cat will make off with it, or 3) It will, eventually, after thousands and thousands of rounds, wear out. So for this price, pick up several so you never have to cram rounds in by hand."
