WTB Smith Wesson M19 4inch barrel

Hello folks!

For an upcoming independet movie production, our protagonist owns a S&W M19 Revolver.
As firing prop we have a german EGR77 from Erma, beautiful blank revolver.

Now I am searching for a stunt prop and hero prop for that S&W M19.
Means I am searching for different models, cheap, plastic, metal, beautiful Kokusai Modelgun, or cheap plastic airsoft, or high quality airsoft...
It just needs to look like a S&W M19 like this Tanaka Airsoft

This is a M29 with 8" Barrel... but not expensive and very interesting....

Thank you Chris for the hint!
But a 8inch M29 wouldn't even be a good stunt prop for the 4inch M19. It is much bigger and longer
Would be quite obviously not the same gun.
But thanks anyway!
