Have you ever carried a S&W Sigma 9 or similar IWB w

I am a average framed guy and I typically wear a standard t-shirt. My EDC is a Sigma 9 OTWB but I want to start carrying more concealed so it prints less. How comfortable would it be with this firearm, or should I move to something more compact? via /r/CCW http://ift.tt/2dFpbZ0
