You may imitate, but you'll never duplicate a Ruger. The little Ruger Bearcat is by far one of the neatest, smoothest actioned revolvers out there. They have been referred to as a "mechanical jewel". True, factory issued ones do not come with adjustable sights, but I have heard of them being installed by a good gunsmith. Mostly used by the trapping crowd, but lots of small-handed folks love them as well. A really pretty little .22 revolver....
