Lever action : R92s are smoother, Henry Steel Side Gate are clunkier
Exterior finish: Mostly good, samples of uneven quality with either brand. The color of R92 hardwood furniture can range from brown to reddish to plum. Henry Steel Side Gate tends to have a uniform plain walnut colour.
Interior: R92 may have sharp edges in the loading port
Dimensions: R92s have a shorter LOP (12.5") , Henry's around 14"
Weight: R92s are lighter and handier
Barrel twist: Slower twist with R92s and tighter with Henrys
Subjective: R92s look better than a plain Henry Steel Side gate (the case-coloured is way nicer). I wouldn't pay full retail on either brand. Very happy with the looks and quality of my stainless 16" and 20" R92s 357 mag and the case-coloured 16" Henry 357 mag.
