Was worried about fit but it dropped right in on my G17 Gen4. Works perfectly after a few hundred rounds. Very pleased.

Did a lot of research before pulling the trigger on this purchase (pun intended). Read reviews on 3 different sites, watched YouTube videos, and ultimately went with polymer80warehouse.com because of the price and shipping speed. Not disappointed. Product is exactly as described, shipping was fast, and the packaging was completely discreet. Already eyeing a few more items in their Glock Switches section.
