Think of chunkiness as you would the aspect ratio of a tire. A 215 width tire that is a 70 series looks skinny when compared next to a 215 that is a 45 series. Same with the Beretta. Sure it is 1.5" wide, but it is in a 3" tall by 4" long pistol rather than 1.5" wide in a 5" tall by 7" long pistol. A girl can look pretty darn good at 155 lbs if she is 6' tall, but pack that 155 on a shotgun frame (4'10") and most people would consider that chunky. Same thing.
