OK, the 24/7 OSS D/S is a gen 1 weapon so the gen 2 mag will not work.
the mag from CDNN appears form the picture to be for a 24/7 C (compact) 24/7 and so it also will not work as it will not lock up as its to short.
Not familiar with the taurus product number ?
you can contact taurus and hopefully they can tell you if its a compact mag.
to confuse matters taurus made a 10 round 24/7 mag for Kalifornia that was the same size as a standard mag but had a block in it to limit it to 10 rounds, these mags will work in full size 24/7 gen 1 .
