One thing I hated about the Glock was the ergonomics of the magazine release. It drove me nuts because I don’t want to adjust my grip in a life and death situation. I got a cheaper extended release and it sucked. So I bought this teardrop model. I have to admit the overall quality was superior to the factor and other extended release I got. The overall function is perfect. I honesty couldn’t have asked for a better ergonomic fix to the factory release. I can’t speak to the holster release aspect. I use it purely as my tactical night gun. I keep it out next to my when I’m home, so it never goes in a holster. I have other guns for that. I highly recommend this part. Huge improvement to my overall satisfaction with the Glock 19.
