Trigger safety does not engage - CMC Triggers Glock Drop-In Flat Trigger

So I did a lot of research on this trigger before I spent the money on it. Had high hopes for it and it looks great. However, after installing into my g43 the very first thing I noticed is the the trigger safety does not engage the frame and the trigger can be pulled to fire without touching the safety at all. For this reason alone I am pulling it out and will try to send it back. Compromising any safety is an automatic no go for me. Also there’s a ton of space between the frame and the shoe causing a lot of lateral movement
