They are the same strength as any recent-production SuperBlackhawk. No problem there.
One issue though: the grip frames are a bit small for coping with full-power 44Mag. At a minimum you NEED to get rid of the black plastic "cheesegrater" grip panels and swap for smooth wood - it takes the same grips as a New Vaquero. There are also some oversize (mainly over-length) grips available, don't recall where, or a lot of people splice in SuperBlackhawk or Bisley grip frames on these guns.
