Looks like I am about convinced that a belly holster will be "moving around" so I need to come off this and locate a proper IWB or OWB holster. I think that the holsters I have on hand carry my Glock 23 too high in my holster and thus the pistol tends to lean away from my body and show thru my shirt. I have purchased a larger size shirt and it still prints thru it. Winter time clothing will probably be no problem with concealment. What type holster do you use (IWB or OWB) that would be really concealable under my shirt? Can I really believe these ads that show a slim waisted fella and he has a concealed weapon under his shirt and you sure cannot tell it? Patches.
