You really have to try to "print noticeably". That's because, no matter how you're packing, no one will notice.
I carried a 4” M-29 in an OWB holster along with 2 speedloaders for a month just for fun. At 5’9” and 145 lbs, it was obvious as hell. It stuck out a mile. No one noticed a thing.
Printing is a total non-issue. People are far too wrapped up in their own lives to spend their time examining you. No one’s looking for guns. No one will notice any bulges under your clothes.
I've been carrying daily since 1988, always OWB and usually under a shirt, since it's hot here. I carry full-size guns - 1911, G17, XD .45, etc. Never a problem, even though I don't take any special care to hide the gun.
