An actual DT10 and DT11 should fit, though the wood may sit a little less proud on the DT11 action as it is wider by a total of 3mm (if memory serves). It does help to have spacers or varying bolts (lengthwise) on hand, as I have seen differences between them. If it is an older model/precursor, such as an ASE there are differences to the stock-bolt and receiving thread/nut, and you'll have to (maybe) chip away at the recess for the bolt in the head of the stock.
@Invictus, there are two Ergosign stocks on Guntrader, one being a large grip with a higher (adjustable) comb for DT11's last time I checked. May suit your needs. I've played with the idea of buying one, but fancy the skeletonised body more. Might go to Portugal to get sorted with a CAS.
