They are a pretty realistic replica that has the additional feature that you can use them for plinking at cans. Heavyish and has the excellent ejection system of the original. Impressively large revolver which was simple for officers and soldiers to learn to use, and which has an very long combat record.
But the pellet or BB version does not go BOOM! and launch a huge lump of lead downrange, so it could be disappointing. And it is not made of steel, and it irritatingly has a non-authentic safety catch. I had one for a while then swapped it with tinbum. For what it is I say that it is a good piece of kit, but not something I would spend all afternoon shooting.
If you want a proper 'shooter' then get one of the Smith & Wessons.
