+1... 47s deep pocket clip is found in the accessory section.
There are others similar to the D25A in the 1AA class like the Thrunite T10S, Malkoff MDC AA, and ZL SC52. I have all but the T10S and although the 47 clip isn't the most attractive, I find it functionally to be the best of the lot for a few reasons - it's real spring steel with by far the greatest range of movement before bending; if over bent it's the easiest to bend back without tools or worries of stripped screw heads or body threads (quite common on the D25s); there's no sharp edges or knurling between clip and body to rip up pants pockets; and it's reversible for baseball cap headlamp duty.
