Just purchased a new 21SF to add to my Glock collection on Sunday. I few things I noticed: the slide was very difficult to release for inspection, the magazine release is now ambidextrous but tends to stick in the release position when pressed in either direction, very difficult to release full magazine. A co-worker also purchased the 21SF from another store and he is experiencing the exact same symptoms. Took it to the range hoping a few rounds might loosen things up but it is still the same. Will contact Glock today and see what they can do. Aside from this, I am very happy with this new mmodel.

As with each of my Glocks - I am 100 satisfied, and love to shoot this newest Glock in my collection. I have not had one single problem, mag release, slide lock, mis-feed, ejections, nothing.. As usual, this Pistol has performed perfectly. I ran a marathon fire test, 50 rounds at 25 yards, under 2 minutes - Everything inside the rings, all but 5 rounds inside 7 ring... If your shooting for complete pin-point accuracy, look for a fully adjustable, compensated 1911, if your looking for a duty / combat pistol - this is one fine pistol. I enjoy the pure simplicity of Glocks, and the tried and true durability / dependability of their firearms... I simply enjoy shooting .45acp more than any other caliber - and the 21SF is great - No issues, including the trigger - it''s a combat / duty purpose built unit - so again, trigger is right for that application. Anyway that''s my 2 cents worth.

I purchased my G21SF November of 2008 because I seriously wanted a CCW with superior stopping power. I was not really considering Glock but of all the guns I was playing touchy/feely with the 21SF felt best in my hand. My gun dealer hooked me up with a great price on a factory recon. and the following weekend I shot it at the range beside my Beretta 92FS. I remembered why I love that big ole bullet when the first round went off. I have been shooting IDPA competitions, SSP/SS with my Beretta and thought that was going to be my full time gun. The G21SF had been relinquished to the CCW role and had not been fired since a tactical class over a year ago. Recently my gun club was running the IDPA classifier that I did not want to shoot the Beretta in and possibly reclassify. I thought it would be best to get the Glock out and shoot it some more as it IS what I carry now. I shot it in the CDP class and shot a better score with it that I had with the Beretta! Need I say any more?
