I'm new here to Glock Talk. Just wanted to introduce myself and say I've been reading this site for a couple of months now and have gained a wealth of information, not only about Glocks but on many other topics as well. I purchased my first Glock nine moths ago. It's a Glock 21sf w/ambi magazine realease. As of yesterday I have put 1000 rounds thru it. So far not one FTF or any other issues. The ambi magazine release drops the mags on both the left and right sides with no issues at all. When I first got the gun they were both a little stiff and would stick occasionally but after the first 20 or so mag drops they smoothed out. I'm looking forward to contributing my experiences as well as learning from the expeiences of others.
