wear/draw too....
If you are a armed professional or a CC license holder, Id take the concealment/duty holster & wear it around the house or apt. Let the weapon be conformed to the holster material.
I wore my Aker Comfort Flex shoulder rig off & on with my 96D .40S&W.
I adjusted the fit & practiced the draw.
It helps if you start with a high quality leather holster or well made Kydex rig.
1
hint for new Kydex or polymer holsters; unscrew/loosen the screws fully, insert the unloaded-cleared firearm, then tighten it up to the desired retention/fit.
I learned that lesson with my new Blade-tech holster & my Ruger GPNY 4" revolver.
Even though the holster shop or factory may have sent the model for that handgun it may still need minor changes.
Don't tighten it back down too much either. It should draw freely but not slip or slide around.
