source for moderators

I picked up my first big bore. It is an Evanix Rex P, 9mm pistol.  It is very loud.  Looking for recommendations for different sources for an appropriate moderator.  I hate this line, but "I need to keep it as inexpensive as possible, but still want it to be long lasting and quiet".  Thanks all.
Good Shootin!

You left out the light weight part from that line of yours. Airgun silencers don't wear out so they will last forever as long as you can remove the lead dust from inside. Cheap and quiet for bigbore that can be bought off shelf does not exist so you'll have to make it yourself. Take a good known design like old Weihrauch and scale it up to 2" diameter, job done. It will be very quiet in a low power gun like Rex P.

From what I can find about that gun I believe that has an m18x1 barrel thread. If that is correct the only 3D printable files I have seen for that threading is at Cults3D for about $10.

If you have a 3D printer then you could print one up for the $10 file cost. If you don't have one then it would probably cost you at least $30 for someone to buy the file and print it out and mail it to you, since the cheapest USPS mailing small box costs $10 these days.
