One of the newer releases from Kiergarten Armory is this S&W #3. The picture does not do the pistol justice. It is really well done, and is (IMHO) possibly one of the most accurately done pistols on the grid.
The pistol comes with a holster, a gunbelt, a shoulder rig, and has free updates as well.
Anyone who grew up watching westerns saw everyone carrying Colt Single Action Armys. The truth is that there were a lot of other handguns out on the frontier, from cap and ball Colts and Remingtons, to top-break Smiths and Merwin & Hulberts.
