My Sp101 is a 3", but I commonly carry it in an OWB that seems to have been designed for te more common 2". The barrel just hangs out the bottom a bit. Never bothered me, as I like minimalist holsters, anyway. I've used ones from High-Noon (IWB), DeSantis (OWB), and Bianchii (OWB). I now have a Simply Rugged that doubles for IWB or oWB, but you asked about others.
