Just installed Freedomworks Pro in Rival....no issues. Works as advertised, little takeup, crisp, short reset.
Added tungsten guide rod, cut 16lb 1911 spring to commander length, for now. Runs smooth, no battering. Wish is was captured.
Adder TF brass backstrap, mag extensions (Aluminum), will try brass for weight.
6lb glock strike spring.
Grip tape on the way.
Trying to get used to carry optics.
