Okay so I'm getting ready to order a stealthgear onyx ventcore IWB holster to try out and I'm not sure which I should get. The standard size onyx ventcore IWB or the new mini size onyx ventcore IWB? Will be used with a Glock 23. Anyone who uses stealthgear holsters have any advice / suggestions? I'd rather not spend $200 to try them both and then have to pay return shipping to send whichever one I don't like back if I can avoid doing so. If it matters I'm 6'1 and 195 pounds just average built not athletic or skinny.
