This is the first time I have heard it describes as accurate....At a less than 16’ range during an actual shooting, a slingshot is accurate. How accurate do you want it to be?
I have the S&W Governor, similar gun, better made. When I shoot 45s it is as accurate as any other revolver I have fired. Mine has two birdshot, then two PDX rounds, then two 45s and yes, I have had training.
Preferably a reliable 2 inch grouping.
