Vezuvio is correct

in IDPA you can shoot the 24/7 pro in ESP or CDP (.45 only)...but you can't shot in SSP (stock service pistol) because the 24/7 pro is a single action first shot pistol---not a da pistol. the point that really gets me is the over-whelming number of guys shooting glocks, or M&P (I shot an M&P 9mm in SSP), or some other da/dao gun that have trigger jobs done on their guns. almost everybody has the trigger on their gun lightened for "gaming" purposes. the end result?....the 24/7 pro trigger, stock from the factory, is heavier than the majority of the trigger pulls on the approved da/sa/dao guns....the stock 24/7 sa trigger is certainly not lighter than any of the tweaked guns, but it's still considered an sa gun, so it cannot compete in ssp.

the ipsc and uspsa rules on the web sites appear to contradict and conflict on the status of the 24/7 pro. the springfield XD is considered an sa gun, and i'll bet the 24/7 pro is as well (i.e. no good for production class). they just haven't updated their web sites.

next up....shooting the .45 24/7 pro in idpa...can't wait to run with the big bore....
