Hudson Mfg. is displaying their new drop-in threaded barrel. It features standard 1/2×28 threads, and is currently being offered for sale with Hudson’s various dealers and distributors. When asked about selling H9s with the barrel installed, a rep stated that Hudson’s current goal is to support the customer base who already purchased an H9, rather than offer a whole new H9 model with the threaded barrel.
Here the barrel can be seen installed in the Hudson H9A, the aluminum framed H9 with polymer grip panels, which shaves off roughly half a pound of weight when compared to the standard H9, and a lower MSRP.
