A week ago we released the Apex Competition Action Enhancement Kit (Comp-AEK). We made the installation walk through today and it’s ready for the world.
Comp Striker Spring Installation
Since the rest of the springs have already been covered, we saw no point in wasting your time with the full instructions, so this video covers the installation of the Apex Competition Striker Spring only.

I was just curious, the competition striker spring kit shows that it is for the s&w m&p, does this also work on the pro model 9mm? What would you recommend, thanks.
