That Firing pin block on the H&R was a good idea, don't know if Henry is using the same design or not. While it Was a Good Idea it was in fact rather poorly designed. Back in the 1980s & 90s when I had an FFL & did some gunsmithing I always kept several of these in stock. The block itself was comparatively heavy but connected to the trigger on only one side by a fairly thin leg. I replaced a good number of these during that time. I don't know if they have improved it by now or not. I have a 30" barreled H&R 12 gauge with the thumb push opener which I inherited. I have not shot it but will say if & when I do it will not be with a 3" Mag, even though it is so chambered. It is simply too lightweight for such power.
