i just threw my buddy's SP101 (same one as the one you are looking at), you'll be able to stand around and walk fine but if you side down you'll definitely print, also people will most likely be able to see the butt of the gun, i have black shorts on and he has black grips on it so it's not that noticeable but it doesn't conceal well. he has a simple IWB leather holster for it and carries it all day, conceals that way very well
