This makes the gun feel like it was made just for My hand. feely nice. It reduces time between shots. I love it

I have a Glock 19 - the description says "fits Glock 9 mm" and the Glock 19 is a 9 mm, but the yellowish aluminum piece did not fit all the way in. Even with some force and lubricant and trying to "knock" it in there were 2-3mm left, where it further needed to be pushed into the handle/grip. I decided to cut of (with a metal hand-saw) the upper portion (approx. 5 mm) - rounded the edges and then it fit in perfectly. I really like the assembly, because the pistol fits so much more better into my hand and I have a 100% better feel & shooting experience. Again - not sure why it did not fit and why I had to cut of a piece in order to make it fit into the handle/grip. Maybe it is not supposed to fit into a Glock 19, but anyway - I was able to make it fit & work. Definitely (if you don''t mind to make that modification) a recommendation. If it would fit without the modifications - I would have rated it 5*.

This is on of my favorite accessories. It looks great, feels great, and is easy to install or remove. It does give more stability, and I think it helps your accuracy because it encourages you to put you hands in the same place consistently.
