Got this for a G23 polymer80 build and have had zero issues with it, but I have only put about 100 rounds thru the gun ( thus the 4 stars ). All in all I'm happy with my purchase.

Nice!

I am giving this 4 stars because when I received this part it did have a bit of break-in time to it. It worked right out of the box, the issue was the noise of the spring scraping the inner guide rod. But once it broke in, it was fine and the sound had worn away...I only had to rack the slide a handful of times and it was golden. I have this in a G20 and a G17, its great!
