I want to stay in the production class I am wondering what changes can be made and stay in that class.

You can change the lighter pull by changing the connector.
You can change the sight.

Anything made by glock is good to go. Connector, springs, mag release etc. Any open sight (including aftermarket) that doesn't require modification of the slide to install. Aftermarket mags are ok.
