Great Trigger drop in!
I'm a certified Glock armorer. This is a very easy to install trigger that provides a nice improvement to the the Glock trigger without compromising function or safety. Punch your three pins, remove slide stop and locking block, and remove the trigger assembly. Gently rotate the trigger and bar to the port side and pull up and out. Remove from trigger spring, install the new trigger and bar, and rotate the it back into place. Ensure the trigger spring isn't bound to the outside of the connector hole, and reinstall the trigger and repeat all steps in reverse. About 1 min if you are practiced. The flat surface and shorter take up make this a very easy trigger to work on my Glock 20SF. It made it easier to tighten up my groups. I'd recommend this drop-in trigger for any Glock owner.
