I can fit a Springfield XDS .45 in a De Santis `sticky’ holster in the pocket of my shorts.
40” waist and I’m 200 lbs. but I think a smaller guy could swing it.
Wear suspenders, under a tee-shirt if you don’t want to look Amish, because it is heavy, unless you want that drooping trousers, `homeboy’ `whigger’ effect.
You can hammer 3/8” brass grommets into the waistband of your bluejeans, or a belt (you may have to flatten the belts attachment points first with a hammer on concrete), and use `cowboy suspenders’ with round spring-loaded hardware.
Or a lot simpler, Perry suspenders (Walmart) that clip onto your belt.
With your hand on the Springfield you can answer, “Maybe.”
My leather jacket and my biker vest both have built in conceal carry pockets. I had trouble carrying my M&P 45 in the vest until I bought some closure extenders.
