This would be helpful (including which shroud lengths they are coming with). Google search is all over the place when it comes to the barrel/shroud lengths.
Also still waiting for the info on spare parts/barrels/shrouds/compensators, etc., and if these have to be purchased for the pre-order or if they can be added in after. Also holding out hope for a default .357 version with a 5" compensated barrel - or a .454 if they make them again. Only a couple of weeks left and the info is pretty sparse.
