Welcome to GT, Doc.
Seen in silhouette, the baby Glock occupies about the same "footprint" as a J-frame or a Detective Special, but in three-dimensional practice, it's distinctly "blockier."
There are lots of makers who produce pocket holsters for baby Glocks. You just need pants capacious enough to hide them, and additional drawing practice so the square back of the slide doesn't snag on the top edge of the pocket.
Make sure you practice a LOT with the EMPTY gun, bringing it out of the pocket, before carrying loaded for the street.
Best of luck,
