This new gun has a full sized cylinder as in the same size as a 45 Colt. The ratchet will be smaller as you can see in the pics, but not as small as the H&R which has a small cylinder to begin with. They say that they have tested it for thousands of rounds with no problem. I have a couple of USFA guns and they are top quality, and have a lifetime warranty. It looks like the ratchet may be attached to the center bushing and it may then be replacable. Not sure of that, just looking at the pictures and voicing opinion. Looks cool to me.
