I’m looking for recommendations for a holster for a Ruger SP101 that I can use on either a waistbelt on a pack, or outside the belt when the pack is not on.
Razco OWB Holsters (razcogear.com) will make one for any of the SP101 barrel lengths. If you have a 2" barrel they are very easy to find from any of the major companies - I have the 3" and that limits options significantly. Just ordered a Razco harness holster this week for my 3".
