The PPQ trigger is excellent out the box for USPSA Production or IDPA SSP. If you drop the Apex kit in, it's no longer Production/SSP. I suppose you could play in Carry Optics but the gun would suck in Open because it doesn't have th 170 mags available for it. They would have to be custom made. IMO, there's no reason to mod the PPQ for the sports. I know a guy who's almost a USPSA Master with a stock PPQ 5".
