It looks cool but I would question that:
1) at half the weight of a .45ACP or .45LC would I not rather have that? Especially a hotly loaded .45LC.
2) Would a .410 slug actually engage the rifling of the pistol (like a .45 ) or would it just start keyholing like crazy shortly after exiting the barrel? Unlike a 12 or 20 gauge, the .410 is truly the caliber or bore size, right?
It looks cool but I wonder if it would actually perform? I would like to see something like the box-of-truth on those.
The Dupo-7 is a sabo design that does engage the rifling. Given its abismal BC, I would guess that the slug would only stabilize for about 50 yards or so.
