    Great bargain on a great OEM part

    Very good product and makes shooting a Glock 21 much more fun. If you are nervous about installing it yourself, don't be. Suggest that you watch any of the tutorials on replacing this part that are available on YouTube. When you do that you will learn the technique for sliding the retaining pin out of the pistol and using the correct size punch you just push the pin out. No effort at all and the replacement part is a straight drop in part. Put it in, push the retaining pin back in place and put the slide back on and your good to go! The extension is comfortable to you, will allow you to put the slide back into battery without a major readjustment of your hand position on the grip and will help you get on target quicker after swapping out magazines.

    Excellent value, very practical and easy to install.

    When using heavy recoil springs it makes it very easy to release the slide with one hand while the original slide release is more difficult to use and requires two hands to release, one to bull the slide, the other to press the slide release down.

    Perfect fit and finish

    Do yourself a favor and replace the old standard slide release. This release only protrudes slightly more than the factory installed release but just that small amount makes all the difference in the world. Not enough to get caught in clothing when carrying off duty. Very inexpensive item and no reason not to install because total installation time is less than 5 minutes.

    Glock OEM Part is Perfect

    Can't go wrong with a Glock OEM part. It fits and works perfectly. Relatively easy to install, and it makes a big difference when using the slide release function. Much easier to release the slide.

    Great Glock Upgrade

    Hello all. This slide lock/release upgrade for my Glock G20sf is awesome. The factory one doesn't quite do the job of releasing the slide so easily, but this upgrade makes it super simple. As soon as I saw this part I had to get it right away. Too bad it doesn't come standard.
