hellcat

Hello. I am new to this site. I am the owner of an XDS mod 2 w/CT and newly a Hellcat OSP. I am looking for recommendations on a good iwb holster for my Hellcat with osp. I have it narrowed down to: We The People iwb Red Dot Optic cut, Crossbreed Reckoning or Crucial Concealment Covert. Any...

The sights are off and I don't see in the manual on where to adjust it. It is shooting 3 inches to the left. I checked YouTube and didn't find anything for the hellcat. How is everyone else adjusting their sights?
