I'm impressed with how well my 43 conceals OWB in a Blade Tech Total Eclipse ($44 on Amazon). This holster will convert to IWB as well. Slightly larger tee shirt and it seems to conceal fine. But I agree with Erich-the curved, rounded lines of a small revolver seem to blend in more naturally to body shapes than the straight lines of a semi-auto which the eye catches as man made. When you go from J frame size to K/L frame it gets tough for me.
