There's several considerations for you to consider.
1. In the case of an open holster, will the muzzle extend past the holster?
2. Will the end of the holster be against clothing, or human skin?
3. Leather or Kydex?
Example: In the case of my latest IWB holster, the muzzle end is open, and the barrel does not extend outside of the leather. The leather is partially resting against skin on one side of the holster. As long as the leather is not used for storage on a dresser, drawer, shelf or otherwise, I'll enjoy it. Kydex is not for everyone.
