Trigger suggestions for Glock 19 Gen 5

I want to eliminate overtravel on my Glock.
This is a carry gun, so I am not looking to change trigger pull weight or to reduce take up.
Reliability is obviously a must.
Any suggestions?

IMHO? Leave it alone, practice your set/reset.

Stock is the most reliable

I would highly suggest you go visit Rock Your Glock and chat with the fellows there. They have various solutions for ya! I am using their Phantom triggers in one of my G19 customs and it is fantastic! Has been totally reliable for thousands of rounds and only a few cleanings.

+1 for Rock Your Glock.

I like post #2 and #3.

But, if a guy was just wanting to reduce the over travel then one of the connectors that have the over travel tab might be an option. Best part is there are no funky extra parts or any fiddly screws to back out and foul things up.

I have read that incorrect overtravel adjustment can cause doubling.
I am struggling to visualize how it could happen from a mechanical standpoint, how parts interaction could cause it...
Anyone has direct experience of this?
Can someone explain?
