The upper part of the 98 DA's mags match that of a Browning Hi Power, but the 98DA mags are a bit longer (ie, you can stick a 98DA mag into a Browning Hi Power and have it protrude a bit).
Unfortuneatly, since they did go with a longer grip you have to buy 98DA specific mags for it. If you'd gotten the 98DAC model you could have using standard HP mags.
