Get an old colt woodsman and have a good smith reset front sights and buy low velocity 22 ammo. The weapon will not function as a semi but rather as a single shot that has to be manually recycled.
Revolvers cannot be suppressed, and fully functioning semis cannot as the escaping gasses from the cycling will cause noise problems. Some delayed blow back ones will though. However you are then using full pressed ammo and that also causes problems at pistol ranges.
Alternative is the suppressed Hi Standard.
Not what you wanted was it.
