I would probably have to ante up some cash for SP5/SD. Hope they will be about the same $ as SP5K.
Keep dreams guys.... nothing wrong with it, just realize it’s still a dream. I think HK’s direction is no where near on bringing a SP5 to market let alone an SD even if you call it something else or it comes as a pistol.
