Assuming that leaving the gun out on a dresser etc. won't allow it to be accessed by other persons, it's all good but a nice litle gun valut isn't a bad choice. The gun does not have to be cleared unless you want to be so, but the more you empty and load, the more you're going to "damage" the bullets by inducing more projectile setback where the bullet itself gets pushed back further and further into the casing when loading multiple times and firing cartridges with "X" amount of setf back can cause and over pressure issue.
the P238 can be pocket carried, but due to it's cocked and locked nature, the hammer channel can become a dust trap and needs to be checked oftern to ensure taht pocket lint will not obstruct the hammer from making contact with the firing pin.
I have a pocket holster from Del Fatti that I've used on occasion but my primary method when carrying the 238 was one of two IWB holsters.
Check out Mika, K&D Leather, UBG, HBE, and Mitch Rosen for pocket holsters. My IWBs were made by HBE and Desibens.
