I'm going to be travelling to SD soon and I am having a hard time discerning what the CCW regulations are, the pinned thread seems to be a bit out of date.  I have a WI CCW.  I see that there is a tiered permit system, but then also a line about residents/non-residents being able to carry without a permit at all.  Can someone give my the rundown?

Thanks

You will be fine with your CCW as we do have reciprocity with WI. That said we are a constitutional carry state.

Only restrictions we have are below, taken from the Secretary of State website.

"Concealed carry is valid throughout South Dakota, except in any licensed on-sale malt beverage or alcoholic beverage establishment that derives over one-half of its total income from the sale of malt or alcoholic beverages (SDCL 23-7-70); any county courthouse or state capitol as defined in SDCL 22-14-22, except as provided in SDCL 22-14-24; or any public elementary or secondary schools (SDCL 13-32-7). The permit is not transferable from one person to another (SDCL 23-7-8.3)."

Great thank you for the clarification.

You're fine. A number of years ago SD changed its law to recognize ALL states' carry permits.
