They will have one in metric thread and one in standard thread . Which is  your suppressor?


NOTE:                The Heckler & Koch VP9A1 X (often called the VP9X) is a "crossover" 9mm striker-fired pistol. It pairs a compact 4.09-inch slide and barrel (from the VP9K) with a full-size grip frame that supports standard 17-round and 20-round magazines, similar in concept to the Glock 19X or Glock 45

I think the barrel you picked is for the longer  slide.   CALL THEM

The VP9A1 X Tactical OR stands out with its 4.7” hammer-forged barrel with threaded muzzle and suppressor-height sights.
