Bigger thread is always better but you cant do a 14mm thread on a 14.3mm barrel and have enough for the suppressor to pull up on to. 14mm thread requires a barrel of at least 15mm.

Unfortunately a police mail order form is now required for "silencers" and a firearms license is required to own one.
1/2-20 or 1/2-28 would be ideal and very common threads.
