Installation instructions
Below I have a couple of videos that will help you install the parts into your ACE fcu and then place the ACE into my grips. If you have any questions, please let me know!
First, you will need an area of your house that will make it easy to find small springs and pins that drop, trust me you will drop them!
Then you need a glock punch or similar sized punch, 3/32 is ideal.
Follow the videos, pausing as needed, and keep the little parts baggie to place your ace parts into.
How to uninstall the FCU
How to install my parts
The Glock backstraps are very, very tight; the method demoed in the video is really the only way to install them. Don't forget to cut down OEM Gen 5 backstraps to clear the fcu!
An important thing to note is that the springs can get bound up and crooked and will create a clicky, odd feeling trigger. If that happens, just make sure the springs are completely straight, and you should be good to go.
