I have a 30 caliber impact but I like my Wildcat a lot better than the impact ,it's lighter easier to handle and feels less delicate I would love to have a wildcat in 30 cal.
I would think the MKII might be adaptable to .30 since it has the X-Barrel System but I have seen nothing of a factory .30 in the making. With the changes in Texas Hunting regulations I also echo your wish! I believe the Dreamline will have a .30 caliber option when it becomes available.
