Benchmark trigger frames for the automag have always been kind of steered clear of. They increase the trigger pull length very significantly and are loose as a noodle. They make the trigger less "hard" but definately just kinda smooshey.
I remember when you could buy benchy 2 finger frames for the mag for like 10 dollars basically new because of these reasons.
Stock mag frame is great. Otherwise, get a double and shoot faster than your tippmann instead of slower
