You'll need an extended, threaded barrel made for your pistol. I have no idea who makes one or if it's interchangeable with another brand. Because of the design of the pistol, you will most likely need a suppressor with a recoil booster for reliable functioning. Make sure the thread pitch of the barrel matches the thread pitch of the suppressor; most manufacturers adhere to the standard thread pitches for the various calibers. Some suppressor manufacturers can also provide a firearm-specific barrel along with the suppressor, for an additional fee of course.
Check the websites that deal with suppressors and suppressed firearms. You'll most likely find all the information you need.
Good luck on your quest.
