I just got my box of parts from Cajun ( It's true , good things come in small packages. ) with everything to make a good crisp SAO SP01 and the trigger is not drilled or tapped for the pre travel screw . It also did not include the slave pin but that's not a big deal as the floating trigger pin came with one . Is no pretravel screw the new normal or is this a slip-up ? Everything else looks good , new sights, race hammer, pins and springs .
