I case this question is aimed at Armory Craft (since it was the last reply before your question:
The answer is yes.
1) STAS- type TDL that will be compatible with all X5, X6, X-Short as well as regular P226 guns. Similar looks but a sligtly different shape that is more holster friendly. Wrapping up the production this week - then off to black nitride QPQ. ETA: - mid March
2) Threaded bull barrels for US as well as German X5s
3) Long/Competition compensator X5 Open style - ETA: April
4) Shorter (2 baffle) compensator - aimed more at recreational shooters - ETA: April
5) Also considering to do the optical bridge, similar to German X5-Open. However, things are bit more complicated since there is no recess at the bottom of the picatinny rail, like we see on German guns. We already have it drawn, including the new type attachment to the frame, but are simply too busy with other products that take a priority in manufacturing at this time..
