If you have to stay Glock, put a red dot on it and shoot production optics.
Glocks can't take major power factor long term.
Been there, done that.
It will work great for a while (assuming its put together properly) then springs start to break and pins start to bend.
Don't get me wrong, it was a really fun gun and I enjoyed shooting it in open, built it up with all the carver open parts.
Ultimately I replaced all the worn out parts and sold it.

Or, a free alternative, just push one of your mag pouches in front of your hip bone and presto, you are in open!
edit,
you posted your response above before I submitted mine.
Sounds like you may not know about Production Optics division.
Might be the right division for you.
Or, definitely upgrade the glock, but stay minor PF in open and have fun.
